Deep Intelligence Across Industries

PAM-XIAMEN is a privately held Chinese supplier of semiconductor substrate and epitaxial wafers. It covers more material systems than almost any other small supplier. Its catalogue runs through three "generations" of semiconductor materials: elemental germanium and silicon; III-V compounds such as gallium arsenide, indium phosphide, indium arsenide, indium antimonide and gallium antimonide; and wide-bandgap silicon carbide and gallium nitride. Around these sit cadmium zinc telluride, SOI, epitaxy, wafer reclaim and foundry services. The company does not compete on high volume with single-material leaders such as Umicore or AXT in germanium, or Wolfspeed in SiC. Instead it serves a long tail of universities, research institutes, start-ups and device makers that need small to medium lots of many different specifications, epi-ready and with a test report. Its strengths are breadth of catalogue, customisation, price competitiveness and an established export business. Its main exposures are Chinese export controls on gallium and germanium, its small scale, and limited disclosure. --- **Disambiguation.** Xiamen Powerway Advanced Material has no connection to Powerway Group of Ningbo (Ningbo Powerway Alloy Material, chaired by Xie Shicai), which makes copper alloys. The company profiled here is the Xiamen-based maker of compound-semiconductor and germanium wafers sold under the PAM-XIAMEN brand. **The company's own description.** PAM-XIAMEN calls itself a leading manufacturer of compound-semiconductor material in China. It says it develops crystal growth and epitaxy technologies, manufacturing processes, engineered substrates and semiconductor devices, and that its technologies allow higher-performance, lower-cost wafer manufacturing. It traces its origins to a state-owned condensed-matter physics research centre that launched the company in 1990. It describes itself as "invested by the leading manufacturers from the fields of advanced and high-tech material research and state institutes and China's Semiconductor Lab". The company claims more than 25 years of experience in compound-semiconductor materials and export. **Independent characterisation.** PAM-XIAMEN is best understood as a substrate and epiwafer manufacturer and merchant with wide catalogue coverage. Its business model combines three things: 1. **In-house crystal growth and wafer processing** for its core materials. For GaAs, the company describes a full line covering VGF crystal growth, cutting, grinding and polishing, with a class-100 clean room for cleaning and packaging. For SiC it describes a line from crystal growth through polishing, cleaning and testing. For germanium it uses VGF and LEC growth. 2. **Epitaxy services**: III-V epitaxy by MBE or MOCVD, SiC homoepitaxy, GaN-on-sapphire templates, GaN HEMT and LED epiwafers, laser-diode epiwafers and silicon epitaxy on 50–150 mm wafers. 3. **Catalogue extension through shared or partner factories** (the company refers to four factories that it "owns and shares"). This covers silicon (FZ, Cz/MCZ, 300 mm, SOI, test and dummy wafers), photomasks, photoresist and foundry services. **Revenue model.** Revenue comes almost entirely from product sales: wafers, ingots, epiwafers and optical blanks. A smaller share comes from services such as custom epitaxy, wafer reclaim and fabrication foundry work. There is no subscription or licensing revenue. The product and service split is not publicly disclosed. Sales are quote-based: the company's listings show minimum order quantities of 1 to 10,000 pieces and T/T (wire transfer) payment terms. **Position in the value chain.** PAM-XIAMEN sits at the materials layer, after refined metals (germanium, gallium, indium) and polycrystalline feedstock, and before device fabrication (fabs, epi houses, solar-cell and detector makers). **Customer types.** These include university and government research laboratories; corporate R&D groups; device makers in LEDs, laser diodes, RF and power electronics; and makers of infrared optics and detectors. The website shows logos of Fraunhofer, Sharp, OSRAM, Power Integrations and IBM, and the US SBIR/STTR programme, under the heading "The World's Most Famous Universities & Companies Trust Us". The nature and size of these relationships are not publicly disclosed. **End-markets served.** **Space and concentrator photovoltaics:** Relevant PAM-XIAMEN materials: Germanium substrates (p-type, 100 mm solar-cell grade) **Infrared optics and thermal imaging:** Relevant PAM-XIAMEN materials: IR-grade germanium wafers and windows **LEDs and laser diodes:** Relevant PAM-XIAMEN materials: GaAs and InP substrates, GaAs LD epiwafers, GaN templates, freestanding GaN, GaN LED epi **RF and power electronics:** Relevant PAM-XIAMEN materials: SiC (semi-insulating and conductive), GaN-on-SiC HEMT epi, vertical GaN, SiC epi **Radiation detection (X-ray and gamma):** Relevant PAM-XIAMEN materials: Cadmium zinc telluride (CZT) **Hall sensors and IR detectors:** Relevant PAM-XIAMEN materials: InAs, InSb, GaSb **Silicon microelectronics, MEMS and photonics:** Relevant PAM-XIAMEN materials: FZ/Cz silicon, silicon epi, SOI, 300 mm, test and dummy wafers **Academic research:** Relevant PAM-XIAMEN materials: Every material system above, sold in small lots and custom specifications

IV IR Optics, the former Photonic Sense, is one of the few independent European producers of optical-grade germanium monocrystals and precision germanium and silicon blanks for infrared optics. In a 3,600 m² plant in Eisenach, Thuringia, it grows large germanium crystals in Czochralski-type pullers: 350 mm diameter routinely and more than 450 mm for special orders. It then machines them on CNC equipment into near-net-shape, ready-to-polish blanks, windows and lens blanks. Its customers are optics makers and system integrators in defence and security, thermography, laser processing, machine vision, medical and life sciences, and automotive. Since September 2021 it has been part of Hellma Materials. Hellma Materials grows calcium fluoride for microlithography in Jena and produces zinc sulphide, zinc selenide and Cleartran® ceramics in Louisiana. With IV IR Optics it can supply most of the main infrared lens materials from a single group. China's export controls on germanium since 2023 have turned the company's Western, non-Chinese crystal capacity into a strategic asset. They also exposed it to raw-material scarcity and record feedstock prices. **What the company does.** IV IR Optics turns germanium metal into optical-grade single crystals and semi-finished infrared optical components. The process starts with high-purity germanium (and, at the predecessor, silicon bought from outside suppliers). The crystals are pulled from the melt by the Czochralski method, oriented and characterised in an in-house crystal laboratory, and then sawn, milled and generated on CNC machines. The output is precision optical blanks: planar and plane-parallel windows, round blanks, spherical and aspheric lens blanks, and near-net-shape blanks supplied "ready for polish". Customers then polish, coat and assemble these into finished lenses, windows, domes and filters for thermal imaging cameras, night-vision systems, laser optics and sensing instruments. **Own description.** The company describes itself as dedicated to producing high-quality germanium and silicon material and precision infrared components. It covers the "complete value-added chain" of germanium and silicon infrared components and handles both prototype quantities and volume production. It stresses short lead times, support for Kanban (pull-based) supply, and high-precision blanks that cut customers' downstream manufacturing cost. It names its end markets as defence and security, health care and life science, laser material processing, machine vision, automotive and other industries. **Independent characterisation.** IV IR Optics is a specialist mid-stream materials processor. It sits between germanium refiners (Umicore, Chinese producers, 5N Plus, recyclers) and infrared optics makers and camera OEMs. It does not refine germanium and is not known to produce finished coated assemblies at scale. Its value lies in crystal quality, which drives low absorption and homogeneity in the 2–14 µm band, in large-diameter capability, and in machining yield. Machining yield matters because germanium swarf and offcuts are valuable and routinely recycled. The business is a niche, capital-intensive, low-headcount operation: about EUR 6 million revenue and 25 employees in 2020. Profitability depends heavily on germanium metal prices and on whether those prices can be passed through to customers. **Business model:** Characterisation: Make-to-order and make-to-stock manufacture of crystalline infrared optical materials and semi-finished parts **Revenue model:** Characterisation: Almost entirely product revenue (crystal blanks and machined components); no disclosed service, subscription or licensing income **Value-chain position:** Characterisation: Mid-stream: refined germanium metal → crystal growth → CNC blank generation → (customer) polishing, coating, assembly → camera or system **Customer types:** Characterisation: Infrared optics manufacturers, thermal camera OEMs, defence electro-optics integrators, laser and photonics component makers, distributors **End markets:** Characterisation: Defence and security (thermal sights, surveillance, vehicle and tank windows); commercial thermography; firefighting cameras; industrial monitoring; laser material processing (CO₂-laser optics); machine vision; automotive night vision; medical and life science; analytical instruments (filters, windows) **Key named customer (historical):** Characterisation: FLIR Systems AB (Sweden), supplied with germanium lenses for thermographic cameras since 2004 **Compliance posture (historical):** Characterisation: Listed as ITAR registered/compliant and TAA-approved for US defence supply

SweGaN is one of Europe's few independent specialists in gallium nitride on silicon carbide (GaN-on-SiC) epitaxial wafers. These are the engineered starting material for high-power, high-frequency transistors used in 5G and future 6G base stations, defence radar and electronic warfare, satellite communications and, more and more, high-voltage power switching for data centres and electric vehicles. Its core asset is QuanFINE®, a patented "buffer-free" heterostructure. QuanFINE replaces the thick, iron- or carbon-doped GaN buffer of conventional epiwafers with a thin GaN channel grown directly on a high-quality aluminium nitride nucleation layer. The company says this gives lower trapping, better carrier confinement and lower thermal resistance. SweGaN sells custom 100 mm and 150 mm epiwafers to IDMs, foundries, fabless designers and system makers in Europe, Asia and the United States from a purpose-built facility in Linköping, sized for up to 40,000 epiwafers a year. Commercially it is still early-stage: net sales were SEK 20.5 million in FY2025 against an operating loss of SEK 45.7 million. It is funded by a syndicate that includes Wallenberg-linked investors, Atlantic Bridge, MediaTek, RFHIC and Wafer Works. --- **What the company does.** SweGaN designs, develops and manufactures GaN-on-SiC epitaxial wafers. An epiwafer is a semi-insulating SiC substrate, bought from third-party substrate makers, on which SweGaN grows a stack of crystalline III-nitride layers by metal-organic chemical vapour deposition (MOCVD). The stack is typically an AlN nucleation layer, a GaN channel and an AlGaN barrier, sometimes with a GaN cap. Customers process these wafers in their own fabs into high-electron-mobility transistors (HEMTs) and monolithic microwave integrated circuits (MMICs). Industry analysts commonly estimate that the epitaxial layer sets around 70% of a compound-semiconductor device's performance. That is why epiwafer design is a point of technical differentiation, not a commodity input. **Company's own description.** SweGaN presents itself as a European semiconductor company that makes custom GaN-on-SiC epitaxial wafers using its proprietary QuanFINE® technology for IDMs and device foundries, fabless companies and system manufacturers. In its funding announcements it describes itself as a Swedish developer and manufacturer of GaN-on-SiC epiwafers for high-performance RF and power electronics. **Independent characterisation.** SweGaN is a merchant ("open-market") epi house. It is not part of a vertically integrated device maker, and that sets its strategic position. The largest GaN-on-SiC device makers (Qorvo, MACOM, NXP, Sumitomo Electric Device Innovations, CETC institutes) grow much of their epitaxy in-house. The open epiwafer market is therefore a smaller pool, served by IQE, Soitec (EpiGaN), SCIOCS/Sumitomo Chemical, NTT-AT, DOWA and several Chinese suppliers. SweGaN's thesis is that a structurally different epi stack can win business even from IDMs with their own reactors. It also argues that rising interest in supply-chain sovereignty in Europe, Korea and Taiwan favours a second-source European supplier. Strategic equity from RFHIC (a Korean GaN RF device maker), MediaTek (a Taiwanese fabless leader) and Wafer Works (a Taiwanese wafer maker) supports that thesis. All three combine customer, partner and investor roles. **Business and revenue model.** **Product sales: custom epiwafers:** Description: QuanFINE® GaN-on-SiC epiwafers made to customer-specified layer designs, sold per wafer under purchase orders and multi-period framework agreements; Relative importance: Core; makes up nearly all net sales **Engineering services:** Description: "Tailored Epi on Demand" design service, material analysis, device processing and characterisation, R&D services for partners; Relative importance: Secondary; split from product sales not publicly disclosed **Publicly funded R&D:** Description: Contributions from Vinnova, the European Space Agency, EU Horizon/Chips JU programmes and Swedish research funders; Relative importance: Booked mainly as other operating income; SEK 3.4 million in FY2025 **Licensing / subscription:** Description: None disclosed; Relative importance: — Framework agreements are the main commercial instrument. The three frame agreements signed in the first half of 2024, the long-term agreement with a global RF GaN chipmaker in the first half of 2025, and the SEK 25 million of framework orders booked in January–April 2026 all set volumes released over 6–18 months. Revenue therefore follows order intake with a lag, and it depends on the customer's own qualification and production ramp. **Value-chain position.** **Semi-insulating SiC substrate:** Typical players: Wolfspeed, Coherent, SICC, SK siltron; SweGaN role: Buyer **MOCVD equipment:** Typical players: Aixtron, Veeco and specialist hot-wall reactor suppliers; SweGaN role: Buyer / process owner **GaN epitaxy:** Typical players: IQE, Soitec (EpiGaN), SCIOCS, NTT-AT, SweGaN, in-house IDM epi; SweGaN role: Core position **Device / MMIC fabrication:** Typical players: Qorvo, MACOM, UMS, NXP, SEDI, RFHIC, foundries; SweGaN role: Customers **Modules and systems:** Typical players: Ericsson, Nokia, Saab, Thales, satellite primes, power-supply makers; SweGaN role: End users and co-development partners **Customer types and end-markets.** **Telecom infrastructure:** Application: GaN power amplifiers for 5G / 5G-Advanced massive-MIMO radios; 6G cm-wave (7–15 GHz) research; Status: Commercial supply under frame agreements; 6G pre-competitive R&D (GaN6G+) **Defence and aerospace:** Application: Radar, electronic warfare, high-power RF; Status: Commercial frame agreements from defence players; Saab is a co-development partner **Satellite communications:** Application: Ka-band MMICs for satellite antennas; LEO constellations; Status: ESA "Kassiopeia" project; commercial supply **Power electronics:** Application: High-voltage (650 V–1,200 V) GaN switches for data-centre power supplies and EV on-board chargers; Status: Orders for data-centre power devices in 2026; 1,200 V device development under the EU ALL2GaN project Customers are not named in company disclosures. The company has said only that they are located in Europe, Asia and the United States. In 2022 it reported more than 30 paying customers and qualification activity across all three regions.

NTT-AT is the technology commercialization arm of Japan's NTT Group. It was founded in 1976 to turn the output of NTT's research laboratories into products, systems and services that can be sold. Annual revenue is about JPY 74 billion and the company has about 2,165 employees. It runs four businesses: application software (led by the WinActor RPA platform), materials and nanotechnology, network and security platforms, and systems integration. The materials and nanotechnology business is small relative to the whole company, but it gives NTT-AT a specialist position in compound-semiconductor and lithography-adjacent materials. Its products there include AlGaN/GaN and InAlN/GaN HEMT epitaxial wafers on silicon (up to 8 inch), SiC, sapphire and native GaN substrates; EUV and X-ray multilayer optics; nanoimprint molds and high-refractive-index nanoimprint resins; optical adhesives; and silicon-photonics foundry services. Market studies regularly list NTT-AT among the main suppliers of GaN-on-Si and GaN-on-SiC epiwafers. Its distinguishing features are direct access to NTT laboratory crystal-growth know-how, low-leakage buffer technology, and a research-grade, small-lot, multi-substrate offering. It does not compete as a high-volume epitaxy foundry. ### What the company does NTT-AT describes itself as a company that works closely with the NTT laboratories and turns their research output into systems, services and products with market value. Its customers include central government, local governments and private companies across many industries. Alongside the work it does for NTT Group, it runs its own businesses as a multi-disciplinary engineering group covering network development and construction, systems solutions, and product development and sales. Corporate materials describe the company as one of only three NTT Group companies, out of more than 900, that work directly with NTT's laboratories. The company's mission statement is "未来を拓くチカラと技術" (the power and technology to open up the future), and its stated ambition is to become an advanced ICT provider. ### Business model and revenue model | Revenue stream | Nature | Representative offerings | |---|---|---| | Contract development and engineering services | Project and time-and-materials revenue, much of it from NTT Group operating companies (NTT East, NTT West and their subsidiaries) | DX tool development for NTT East/NTT-ME; network and server design and construction for municipalities and universities | | Software licensing and subscription | Per-licence and SaaS revenue | WinActor RPA (more than 8,000 customers by March 2024), WinActor Manager on Cloud, @DeAnoS SaaS, RelAi generative-AI tools, XCockpit attack-surface management | | Managed and operational services | Recurring service revenue | ICT-24 Operations Center 24/7 monitoring (transferred to subsidiary NTT-AT Systems from 1 July 2026), SOC and CSIRT support, security diagnostics | | Product sales (materials, components and equipment) | Unit and lot sales, custom orders | GaN HEMT epiwafers, EUV/X-ray optics, nanoimprint molds and resins, optical adhesives, fiber-optic connector cleaners (CLETOP, NEOCLEAN), KTN optical devices, FR-1200 microphones, facility-maintenance coatings | NTT-AT is a hybrid technology company. Its revenue comes from four streams: **Contract development and engineering services:** Nature: Project and time-and-materials revenue, much of it from NTT Group operating companies (NTT East, NTT West and their subsidiaries); Representative offerings: DX tool development for NTT East/NTT-ME; network and server design and construction for municipalities and universities **Software licensing and subscription:** Nature: Per-licence and SaaS revenue; Representative offerings: WinActor RPA (more than 8,000 customers by March 2024), WinActor Manager on Cloud, @DeAnoS SaaS, RelAi generative-AI tools, XCockpit attack-surface management **Managed and operational services:** Nature: Recurring service revenue; Representative offerings: ICT-24 Operations Center 24/7 monitoring (transferred to subsidiary NTT-AT Systems from 1 July 2026), SOC and CSIRT support, security diagnostics **Product sales (materials, components and equipment):** Nature: Unit and lot sales, custom orders; Representative offerings: GaN HEMT epiwafers, EUV/X-ray optics, nanoimprint molds and resins, optical adhesives, fiber-optic connector cleaners (CLETOP, NEOCLEAN), KTN optical devices, FR-1200 microphones, facility-maintenance coatings The company does not publish the mix between product, service, subscription and licensing revenue. On an independent reading, services and software make up most of revenue. The FY3/2026 cost of sales was 83% of revenue, which fits a labor-intensive engineering-services company. Materials and devices are a high-value niche within the portfolio. ### Value-chain position in semiconductors In the semiconductor supply chain, NTT-AT works at the materials and front-end enablement layer: **Epitaxy:** It grows III-nitride heterostructures (AlGaN/GaN and InAlN/GaN HEMT stacks) by MOCVD on purchased substrates and sells device-ready epiwafers to device makers, research institutes and universities. It also offers device fabrication and materials analysis for those wafers. **Lithography and metrology enablement:** It supplies EUV and soft X-ray multilayer mirrors, beam splitters, dichroic and toroidal mirrors, transmission gratings, Fresnel zone plates and X-ray resolution charts. Users include EUV source developers, metrology tool makers, synchrotrons and high-harmonic-generation laboratories. It also supplies nm-scale beam-size measurement artefacts and length-calibration scales for scanning probe microscopes. **Nanoimprint and optical materials:** It sells catalog and custom nanoimprint molds, UV-curable high-refractive-index resins (the NH700 series, refractive index up to 1.9), and optical adhesives and sealants for photonic packaging. **Silicon photonics:** It provides silicon-waveguide foundry services for R&D and fiber-attach services for photonic chips. **Analysis standards:** It supplies multilayer depth-profiling reference samples for SIMS, AES, XPS and XRF, and SiC/SiN membranes for X-ray and electron-beam analysis. ### Customer types and end-markets | Customer type | End-markets served | |---|---| | NTT Group operating companies | Telecom network operations, DX, IOWN all-photonics network rollout | | Central government and municipalities | Local-government DX, assembly digitization (Discuss product family), disaster prevention and evacuation alerts (@InfoCanal), defense research (HPEM/EMP testing) | | Enterprises | RPA and AI automation, cybersecurity, OT security, cloud integration | | Semiconductor device makers and research institutes | GaN power and RF devices, EUV lithography R&D, X-ray microscopy, synchrotron optics | | Optical component and AR/VR makers | Optical adhesives, nanoimprint waveguides for AR headsets | | Facilities and infrastructure owners | Heat-reflective and super-hydrophobic coatings, corrosion protection, hydrogen piping research | **NTT Group operating companies:** End-markets served: Telecom network operations, DX, IOWN all-photonics network rollout **Central government and municipalities:** End-markets served: Local-government DX, assembly digitization (Discuss product family), disaster prevention and evacuation alerts (@InfoCanal), defense research (HPEM/EMP testing) **Enterprises:** End-markets served: RPA and AI automation, cybersecurity, OT security, cloud integration **Semiconductor device makers and research institutes:** End-markets served: GaN power and RF devices, EUV lithography R&D, X-ray microscopy, synchrotron optics **Optical component and AR/VR makers:** End-markets served: Optical adhesives, nanoimprint waveguides for AR headsets **Facilities and infrastructure owners:** End-markets served: Heat-reflective and super-hydrophobic coatings, corrosion protection, hydrogen piping research ### Independent characterization NTT-AT is best understood as an ICT services and software company with a deep-tech materials subsidiary business attached. Earnings are steady and low-margin: operating margins rose from 4.1% to 4.8% over five years. The parent receives roughly the full prior-year net income as dividends. In semiconductors, NTT-AT is a specialist, research-grade epiwafer and optics supplier, not a high-volume materials house. It makes no photoresists, CMP slurries, process gases or packaging substrates. Its nearest overlaps with the semiconductor-materials category are GaN epitaxial wafers, nanoimprint resins and molds, optical adhesives, and EUV/X-ray optical components. Its relevance to the GaN epiwafer market comes from its NTT-laboratory lineage, its range of substrates, and its 8-inch GaN-on-Si capability, not from scale.

Enkris Semiconductor is a pure-play gallium nitride (GaN) epitaxial-wafer foundry. Founder Dr. Kai Cheng, a pioneer of GaN-on-silicon epitaxy, started it in Suzhou Industrial Park in 2012. The company grows and sells epiwafers but does not make devices. It supplies GaN-on-Si, GaN-on-SiC, GaN-on-sapphire and GaN-on-GaN epiwafers to device makers, foundries and research institutes. Its products serve power electronics, RF, micro-LED displays and, from 2026, micro-LED optical interconnects for data centres. Enkris has a record of world firsts. It launched the first commercial 200 mm GaN-on-Si HEMT epiwafers in 2014 and demonstrated 300 mm GaN-on-Si HEMT epiwafers rated 200 V to 1,200 V in 2021. It describes itself as the only supplier worldwide able to provide 300 mm GaN epiwafers. The company reports more than 150 customers worldwide and over 900 patent applications. Strategic investors include Goertek, SAIC Motor, NIO Capital and Meituan Dragonball, which places Enkris at the centre of China's push for domestic third-generation semiconductor supply. --- ### What the company does Enkris designs and grows epitaxial layer stacks of gallium nitride and related III-nitride alloys (AlGaN, InGaN, AlN) on substrate wafers. It uses metal-organic chemical vapour deposition (MOCVD) reactors and sells the finished epiwafers. Customers then pattern, etch and metallise these wafers into transistors, LEDs and other devices. In the semiconductor value chain, Enkris sits between substrate suppliers upstream (silicon, silicon carbide, sapphire and native GaN wafer makers) and device makers downstream (integrated device manufacturers, fabless companies using foundries, and wafer foundries). The company describes itself as dedicated to developing and producing high-quality GaN epitaxial materials for power electronics, micro-displays and similar applications. It calls itself the only global supplier able to provide 300 mm GaN epiwafers. Its Chinese-language corporate materials say it has built China's leading-scale GaN epitaxial materials R&D and production base. ### Business model and revenue model | Revenue type | Description | Estimated weight | |---|---|---| | Standard epiwafer sales | Catalogue GaN-on-Si power HEMT, GaN-on-sapphire/Si LED and GaN-on-SiC RF epiwafers sold per wafer | Core; exact mix not publicly disclosed | | Custom epitaxy (foundry) | Customer-specified layer stacks grown to order, including R&D lots for universities and institutes | Material; Enkris describes itself as a "pure-play epi-foundry" | | Development / qualification programmes | Joint development with device makers and research partners, such as micro-LED validation with Raysolve, RF modelling with Incize and optical interconnect work with SINANO | Supporting | | Licensing | No licensing revenue disclosed.

Its large patent portfolio could support licensing in future; Estimated weight: Not publicly disclosed The model is product revenue. There is no subscription component. Enkris does not make devices, which is its main difference from integrated GaN players such as Innoscience. It is a neutral supplier, so it can sell to device companies that compete with each other. ### Customer types and end markets | Customer type | Examples of demand | |---|---| | Power device IDMs and fabless companies | 100–1,200 V GaN HEMTs for fast chargers, data-centre PSUs, on-board chargers, DC-DC converters, solar and storage inverters | | RF device makers | GaN-on-SiC and low-loss GaN-on-Si HEMTs for wireless infrastructure | | Micro-LED / micro-display developers | RGB and monochrome micro-LED arrays for AR/MR glasses and micro-displays | | Optical interconnect developers | Micro-LED light sources for short-reach, "wide-and-slow" data-centre links | | Universities and research institutes | Custom epiwafers for device research (Enkris lists collaborations with EPFL and Chinese Academy of Sciences institutes) | **Power device IDMs and fabless companies:** Examples of demand: 100–1,200 V GaN HEMTs for fast chargers, data-centre PSUs, on-board chargers, DC-DC converters, solar and storage inverters **RF device makers:** Examples of demand: GaN-on-SiC and low-loss GaN-on-Si HEMTs for wireless infrastructure **Micro-LED / micro-display developers:** Examples of demand: RGB and monochrome micro-LED arrays for AR/MR glasses and micro-displays **Optical interconnect developers:** Examples of demand: Micro-LED light sources for short-reach, "wide-and-slow" data-centre links **Universities and research institutes:** Examples of demand: Custom epiwafers for device research (Enkris lists collaborations with EPFL and Chinese Academy of Sciences institutes) The company reports more than 150 well-known customers worldwide and says it works with hundreds of semiconductor companies, universities and research institutes. Customer names and concentration are not publicly disclosed. ### Independent characterisation Enkris is best seen as a technology-led merchant epi house. Its main strengths are large-diameter strain engineering (crack-free, low-bow GaN on 200–300 mm silicon) and bandgap and polarisation engineering for long-wavelength InGaN (red and green on silicon). In the merchant GaN epiwafer market its closest global peers are IQE (UK), Soitec/EpiGaN (Belgium/France), SweGaN (Sweden), DOWA Electronics Materials and NTT-AT (Japan). In China it competes with CETC 13 and CETC 55, Runxin Microelectronics, Suzhou Nanowin and Qingdao Cohenius. Its strategic investors include a smart-wearables OEM (Goertek), two automotive groups (SAIC, NIO) and consumer-internet investors. This mix reflects the company's three demand pillars: AR/micro-display, automotive power electronics and consumer power conversion.

Innoscience is the world's largest gallium-nitride (GaN) power semiconductor company by revenue. It is an integrated device manufacturer (IDM) and controls epitaxy, wafer fabrication, device design, packaging, testing and failure analysis in-house. It was the first company in the world to mass-produce 8-inch GaN-on-silicon wafers, and it runs the largest dedicated GaN power fabrication base in the world, in Suzhou and Zhuhai. Its products cover the full voltage range from 15V to 1,200V. They sell into consumer fast-charging, smartphones, household appliances, AI data-centre power, automotive electronics (LiDAR, on-board chargers, 48V systems), industrial motor drives, energy storage and humanoid robots. The company sells finished discrete devices and integrated circuits, power modules and 8-inch GaN wafers. The wafer sales place it in both the power-device market and the GaN epitaxial-wafer market. Revenue rose from RMB68.2 million in FY2021 to RMB1,213.3 million in FY2025. Gross margin turned positive in FY2025, and operating cash flow turned positive in 1H2026. The company is still loss-making at the net level. It is also in a multi-jurisdiction patent conflict with Infineon, the incumbent European GaN leader. --- ### What the company does Innoscience designs, develops and manufactures GaN power semiconductors on 8-inch (200mm) silicon substrates. Gallium nitride is a wide-bandgap material. Compared with silicon MOSFETs and, at several voltage nodes, silicon carbide, it switches faster, has lower on-resistance per unit area and has lower switching losses. This lets customers build smaller, cooler and more efficient power converters. Innoscience makes GaN-on-Si high-electron-mobility transistors (HEMTs) in its own fabs and sells them in four forms: 1. **GaN discrete devices and GaN integrated circuits.** These are packaged transistors and driver-integrated GaN ICs sold to power-supply makers, OEMs and Tier-1s. They were 42.0% of FY2025 revenue. 2. **GaN modules.** These are system-level power modules combining GaN devices, drivers and passives, sold mainly into charger, adapter and power-supply applications. They were 36.8% of FY2025 revenue. 3. **GaN wafers.** These are 8-inch GaN-on-Si wafers, processed or epitaxial, sold to other semiconductor companies that package or brand devices themselves. STMicroelectronics is a disclosed user of Innoscience 700V wafers. They were 20.9% of FY2025 revenue. 4. **Other.** Services and minor items, 0.3% of FY2025 revenue. ### The company's own description In its listing documents and annual reporting, Innoscience describes itself as a GaN power semiconductor IDM. It says it is the only company with industrial-scale capacity across the full voltage spectrum of GaN-on-Si products and owner of the world's largest GaN power semiconductor production base. It states its mission as leading the "power semiconductor revolution" by bringing GaN into mainstream markets at high performance and low cost. ### Independent characterisation Innoscience is best understood as a volume-and-cost GaN manufacturer that is moving from consumer electronics into higher-value industrial, automotive and AI-infrastructure sockets. Its strategy rests on manufacturing scale. In early 2026 the Suzhou site was reported to run 15,000 8-inch wafers per month at a stable yield of about 97%. Supply-chain reporting suggests its price quotes are around half those of other global GaN suppliers. Most Western GaN competitors (Navitas, EPC, Cambridge GaN Devices, and historically GaN Systems) are fabless or asset-light and depend on foundries such as TSMC, which has said it will leave GaN foundry work by 2027. Innoscience owns its capacity. That gives it a structural cost and supply-assurance advantage. It also means heavy fixed costs: depreciation and amortisation of about RMB500 million a year was the main reason gross margin stayed negative until 2025. ### Revenue model | Revenue type | Share of FY2025 revenue | Notes | |---|---|---| | Product sales: discretes and ICs | 42.0% | Per-unit device pricing, design-win driven | | Product sales: modules | 36.8% | Higher content per end product; fastest-growing line in FY2025 | | Product sales: wafers | 20.9% | Wafer-level sales to other IDMs and fabless firms | | Services, licensing, subscription | about 0.3% | Not material | **Product sales: discretes and ICs:** Share of FY2025 revenue: 42.0%; Notes: Per-unit device pricing, design-win driven **Product sales: modules:** Share of FY2025 revenue: 36.8%; Notes: Higher content per end product; fastest-growing line in FY2025 **Product sales: wafers:** Share of FY2025 revenue: 20.9%; Notes: Wafer-level sales to other IDMs and fabless firms **Services, licensing, subscription:** Share of FY2025 revenue: about 0.3%; Notes: Not material Revenue is almost all product-based and recognised on shipment. There is no material recurring, subscription or licensing income. ### Value-chain position Innoscience covers the chain from substrate-level epitaxy (MOCVD growth of GaN on silicon) to finished modules. Upstream, it depends on silicon substrates, MOCVD reactors, process gases (ammonia, trimethylgallium and other metal-organic precursors) and lithography and etch tools. Downstream, it sells to: - charger and adapter brands and ODMs, including Anker and Ugreen; - smartphone OEMs (OPPO, vivo, Xiaomi), for over-voltage protection and fast charging; - automotive LiDAR makers (Hesai, RoboSense) and Tier-1s such as United Automotive Electronic Systems (UAES); - energy-storage and battery companies, with CATL its largest customer in FY2023 at 32.1% of revenue; - data-centre power supply makers and hyperscaler hardware platforms (Google design-ins; NVIDIA 800 VDC ecosystem); - other semiconductor companies buying wafers or co-developing, including STMicroelectronics and onsemi. ### End-markets served | End-market | Representative applications | FY2025 / 1H2026 evidence | |---|---|---| | Consumer electronics | USB-PD fast chargers, smartphone OVP, laptop adapters, audio, white goods | RMB568.1 million in FY2025, the largest end-market.

DOWA Electronics Materials is a Japanese materials maker built on more than a century of non-ferrous smelting. It turns metals into high-value powders, crystals and devices. Its semiconductor business runs from ultra-high-purity gallium and indium through VGF-grown gallium arsenide (GaAs) substrates and GaN-on-Si HEMT epitaxial wafers to near-infrared LEDs, photodiodes and deep-ultraviolet LEDs. Its electronic-materials business makes silver powder for photovoltaic electrodes, where it has held a world-leading share, as well as silver oxide and conductive copper powders. Its functional-materials business makes metal magnetic powder for data-storage tape, carrier and ferrite powders, reduced iron powder and perovskite-type complex oxide powder for solid-oxide fuel cells. The company's main structural advantage is its position inside the DOWA recycling and smelting loop. Gallium comes from zinc-smelting by-products and GaAs scrap, and precious metals come from group refineries. Supply security therefore matters as much as technology when China restricts gallium exports. Its main weakness is earnings volatility: silver-powder volumes and pass-through pricing dominate segment sales, while the profit pools are shifting toward fuel-cell materials and optical sensors. Fiscal years end on 31 March. DOWA Holdings' own materials label the year ended 31 March 2026 "FY2025". In this profile, years are labelled by year-end (FY3/2026 = April 2025 to March 2026). **What the company does.** DOWA Electronics Materials develops, manufactures and sells materials whose value comes from purity, crystal quality and particle control rather than tonnage. DOWA Holdings' Annual Securities Report for FY3/2026 describes the Electronic Materials segment as running three businesses: **Semiconductor:** high-purity metals, compound semiconductor wafers and LEDs **Electronic materials:** silver powder and related conductive materials **Functional materials:** magnetic powders and related products The report lists the segment's main group companies as DOWA Electronics Materials, DOWA Hightech (conductive and battery materials), DOWA Semiconductor Akita, DOWA IP Creation, DOWA F-Tec and DOWA Electronics Okayama. In recruiting materials, the company describes itself as producing "high value-added, world top-share product groups" across three pillars. Its own breakdown is: **Semiconductor:** a materials unit for gallium and indium metal, a compound unit for GaAs substrates, and an opto unit for infrared and deep-UV LEDs **Electronic materials:** silver powder for solar-cell electrodes and silver oxide for button batteries **Functional materials:** magnetic recording materials, carrier powder, ferrite powder, reduced iron powder and complex oxide powder for fuel cells **Business model.** The model is mainly product sales. Some products are priced on a metal pass-through basis, mainly silver powder and high-purity metals, where revenue tracks the metal price. Others are priced on value, including LEDs, photodiodes, epitaxial wafers, magnetic powders and fuel-cell oxides. Licensing and service income is not material to segment disclosures. One exception emerged in FY3/2026: paid-sample income on nano-silver development. Management said a customer's inventory adjustment cut that income by about ¥2.1 billion of segment ordinary income in FY3/2026, and it expects a further ¥2.0 billion decline in FY3/2027. **Revenue mix (independent characterisation).** The company does not disclose product-level revenue. Segment sales fell 36.6% in FY3/2026 when silver-powder sales dropped, then more than doubled year on year in Q1 FY3/2027 when silver-powder volume recovered (Q1 volume index 127 against 100 a year earlier). That pattern shows silver powder is the largest single revenue line by value. Value-priced optical devices, magnetic powder and complex oxide powder are smaller in sales but now drive most of the profit improvement. **Value-chain position.** DOWA Electronics sits upstream of device makers and downstream of the group's smelters and recyclers: **Inputs:** gallium recovered within the group from zinc-smelting by-products and compound-semiconductor scrap, silver from group refining, and iron, copper and other metal feedstocks **Outputs:** materials for wafer fabs and epitaxy houses (Ga, In, GaAs substrates, GaN epiwafers), for solar-cell and paste makers (silver powder), for wearable-device and sensor module makers (near-IR LEDs and photodiodes), for tape-media makers (magnetic powder), for toner and copier makers (carrier powder), and for SOFC stack makers (complex oxide powder) **Customer types and end-markets.** **Photovoltaics:** Products: Silver powder for electrode paste; Demand driver (company commentary FY3/2026–Q1 FY3/2027): Chinese price competition; company dropped its China share goal and is targeting customers outside China and silver-saving conductive powders **Wearables and consumer sensing:** Products: Near-IR LEDs, photodiodes; Demand driver (company commentary FY3/2026–Q1 FY3/2027): New products launched in Q2 FY3/2026; next generation targeted for mass production in H1 FY3/2027 **AI data centres (on-site power):** Products: Perovskite-type complex oxide powder for SOFCs; Demand driver (company commentary FY3/2026–Q1 FY3/2027): Demand rising sharply as data centres add on-site generation, mainly in North America; price revisions; full-scale supply from FY3/2027 **Data storage:** Products: Metal magnetic powder for tape; Demand driver (company commentary FY3/2026–Q1 FY3/2027): Demand improving on HDD shortages and rising tape demand **AI servers / information and communications:** Products: Semiconductor and conductive products; Demand driver (company commentary FY3/2026–Q1 FY3/2027): AI-server demand described as solid **Compound semiconductors (RF, power, optoelectronics):** Products: High-purity Ga/In, GaAs substrates, GaN-on-Si HEMT epiwafers; Demand driver (company commentary FY3/2026–Q1 FY3/2027): Gallium supply security, GaN power-device adoption **Batteries:** Products: Silver oxide (button cells), battery materials; Demand driver (company commentary FY3/2026–Q1 FY3/2027): Mature (silver oxide); developmental (solid-electrolyte and cathode-coating materials) **Printing and imaging:** Products: Carrier powder, ferrite powder; Demand driver (company commentary FY3/2026–Q1 FY3/2027): Mature

Yunnan Germanium is China's most vertically integrated germanium producer. It mines germanium-bearing lignite in Lincang, Yunnan, and runs every stage from enrichment, purification and zone refining to finished products. Those products cover infrared optics, space-grade solar substrates, optical-fibre chemicals and III-V compound semiconductor wafers. The company says it ranks first in China by germanium product sales volume, and MIIT has named it a national "manufacturing single champion" (6th batch). Germanium price cycles once drove its earnings. Since 2025 the investment case has rested on its majority-owned subsidiary Yunnan Xinyao, a domestic supplier of indium phosphide (InP) and gallium arsenide (GaAs) substrates. Demand for 800G/1.6T optical transceivers in AI data centres has turned InP into a scarce material. Revenue for the first nine months of 2026 reached RMB 1,363.7 M (+70.7%), net profit rose almost nine-fold, and two disclosed InP supply agreements together exceed RMB 1.8 bn. At about RMB 47 bn, the equity value is roughly 29 times 2026 year-to-date revenue run-rate. The valuation therefore assumes that InP capacity expansion, raw-material access and export licensing all work out. --- ### The company's own description (2025 Annual Report) According to the 2025 annual report, the company's main business is germanium mining, pyrometallurgical enrichment, hydrometallurgical purification, zone refining, deep processing and R&D, plus deep processing and R&D of compound semiconductor materials. Ore mined from its own mines and rough-processed intermediates are not sold. They are used only as feedstock for the group's downstream operations. The company describes itself as the listed germanium company with the most complete industry chain in China, with rich, high-quality germanium resources. It says its germanium output and sales rank first nationally and that it is the country's largest producer and supplier of germanium products. Three subsidiaries hold MIIT "Specialised, Refined, Distinctive and Innovative" (专精特新) "Little Giant" status: Kunming Yunge High-Tech and Yunnan Zhongke Xinyuan Crystal Materials are key Little Giants, and Yunnan Dongchang Metal Processing is a Little Giant. ### Product families and applications | Product family | Main products | Principal end-uses | |---|---|---| | Material-grade germanium | Zone-refined germanium ingot, germanium dioxide (GeO2) | Feedstock for infrared optics, solar wafers, fibre chemicals and catalysts | | Infrared-grade germanium | Germanium single crystals and blanks, coated lenses, lens assemblies, thermal imagers, optical systems | Thermal imaging, defence and security optics, industrial sensing | | Photovoltaic (PV)-grade germanium | Germanium substrates (4-inch and 6-inch) for multi-junction solar cells | Space solar arrays, including low-earth-orbit (LEO) communication satellites | | Fibre-grade germanium | High-purity germanium tetrachloride (GeCl4) | Dopant for optical-fibre preform manufacture | | Compound semiconductor materials | GaAs wafers (1–6 inch), InP wafers (2–4 inch) | LEDs, VCSELs, high-power lasers, RF devices, optical-communication lasers and detectors | The group reports revenue in five product families plus "other": **Material-grade germanium:** Main products: Zone-refined germanium ingot, germanium dioxide (GeO2); Principal end-uses: Feedstock for infrared optics, solar wafers, fibre chemicals and catalysts **Infrared-grade germanium:** Main products: Germanium single crystals and blanks, coated lenses, lens assemblies, thermal imagers, optical systems; Principal end-uses: Thermal imaging, defence and security optics, industrial sensing **Photovoltaic (PV)-grade germanium:** Main products: Germanium substrates (4-inch and 6-inch) for multi-junction solar cells; Principal end-uses: Space solar arrays, including low-earth-orbit (LEO) communication satellites **Fibre-grade germanium:** Main products: High-purity germanium tetrachloride (GeCl4); Principal end-uses: Dopant for optical-fibre preform manufacture **Compound semiconductor materials:** Main products: GaAs wafers (1–6 inch), InP wafers (2–4 inch); Principal end-uses: LEDs, VCSELs, high-power lasers, RF devices, optical-communication lasers and detectors ### Business and revenue model Almost all revenue comes from product sales. Equity research covering 2021–2025 notes that the annual reports show direct sales making up 100% of revenue each year, with no distributor channel. There is no meaningful service, subscription or licensing revenue. A small new biotechnology venture (Yunge Biotech, December 2025) will sell organic-germanium personal-care products. Pricing for material-grade and fibre-grade products follows germanium metal prices closely. Infrared lens assemblies, space solar substrates and InP wafers are priced on specification and qualification. In 2025 the PV customer base moved from annual tenders to monthly tenders or toll-processing arrangements. ### Value-chain position The company owns upstream mining rights, chiefly the Dazhai germanium mine and the Zhongzhai mine in Lincang. It also buys germanium concentrate and scrap from outside, because its own ore does not cover all feedstock needs. Midstream, it refines concentrate into GeCl4, GeO2 and zone-refined ingot. Downstream, it grows single crystals and slices, polishes and coats wafers and optics, and for infrared it assembles lenses and complete thermal imagers. The compound semiconductor chain works differently. The company does not produce gallium, arsenic, indium or phosphorus, and Yunnan Xinyao buys all of its raw materials externally. Here Yunnan Germanium acts purely as a crystal-growth and wafer-finishing specialist. ### Customers and end-markets The top five customers accounted for RMB 392.65 M, or 36.84% of 2025 sales, with no related-party sales. Over 2021–2025 the top-five share ranged from 36.84% to 46.46%, and the largest single customer peaked at 18.35% in 2023. In InP, press reports say Huawei HiSilicon became Yunnan Xinyao's largest customer in 2025, taking about 40% of InP volume. Other customers named in the press include the 13th Research Institute of China Electronics Technology Group, Huaxing Laser and Qianlü Optoelectronics. In November 2026 the US optical-module maker Applied Optoelectronics, Inc. (AAOI) signed a long-term supply agreement for 2027 volumes. End-markets in 2025, by revenue weight: germanium metal and intermediates (34%), optical fibre (19%), space solar (19%), optical communications and other compound semiconductor uses (13%), and infrared (11%). ### Independent characterisation The company is effectively two businesses. The first is a germanium-price-sensitive resource and refining operation, which made up about 87% of 2025 revenue. It has historically produced thin and volatile margins. Material-grade gross margin fell to 4.32% in 2025 as purchased feedstock costs rose faster than selling prices. The second is a small compound semiconductor wafer business, at 13% of 2025 revenue. That business is now in a strong demand cycle: its H1 2026 gross margin reached 47.14% and revenue rose 154.57%. The market capitalisation reflects the second business almost entirely, yet the consolidated accounts are still mostly the first. Who owns the InP business also matters. The listed company holds a majority of Yunnan Xinyao, but Huawei's Hubble Technology owns 23.91% and other minorities hold buy-back rights. A meaningful share of InP economics therefore goes to minority interests.

China Crystal Technologies is one of China's oldest and largest specialist makers of gallium arsenide (GaAs) substrates, the second-generation compound-semiconductor wafers that LEDs, laser diodes, VCSELs, RF power amplifiers and some solar cells are built on. Founded in Beijing in 2004 using imported vertical-gradient-freeze (VGF) crystal-growth know-how, the group now covers the whole chain from gallium metal refining (4N and 6N grades) through polycrystal synthesis and single-crystal growth to finished, epi-ready 2-inch to 6-inch wafers and substrate reclaim. Production runs at five plants in Shanxi, Jiangsu and Guizhou, and the group has trading offices in Hong Kong, Taiwan and Nagoya. The company reports shipments of more than two million wafers a year, with about 65% of volume sold in mainland China and 35% abroad. Its customers include Epistar, OSRAM, ROHM, Nichia, San'an and HC SemiTek. Its strongest position is in optoelectronic (LED and laser) grade substrates, where it claims global volume leadership. It is a qualified but smaller supplier of semi-insulating RF-grade wafers. The company is unlisted and does not publish financial statements. **What the company does.** CCT develops, makes and sells gallium arsenide substrate materials. The group describes itself as one of the earliest Chinese companies whose main business is the second-generation semiconductor material gallium arsenide substrate. It says it broke the technology monopoly of international producers and filled a domestic technology gap. Across its subsidiaries it covers raw-material purification (gallium metal), GaAs polycrystal synthesis, single-crystal growth, wafer slicing, grinding, polishing and cleaning, and the reclaim of used substrates. **Company's own description (corporate website and 2025 corporate profile).** CCT calls itself a "GaAs industry benchmarking enterprise" with about 20 years of accumulated technology covering every key step from crystal growth to wafer processing. It says it is the benchmark enterprise for optoelectronic-use GaAs substrates and a qualified supplier for microelectronic uses. It has exported to Taiwan, Japan, Europe and the United States since September 2014. The group's founding narrative states that it imported proprietary GaAs production technology from the United States and then built its own core processes and key equipment around it. The company says it can make several million 2–6 inch GaAs substrates a year for different applications. **Independent characterisation.** In practice CCT is a volume-oriented, vertically integrated substrate maker. Most of its business is semiconducting (n-type) GaAs wafers for LED and laser-diode epitaxy houses, a market where Chinese makers have taken share from Japanese and German incumbents on cost. It is a smaller participant in the higher-specification semi-insulating (SI) wafer market used for RF front-end ICs, where Freiberger, Sumitomo Electric and AXT/Tongmei dominate. Its backward integration into gallium metal through Yuanping CCT Gallium Industry, a planned 100 t/yr project, distinguishes it from most wafer-only peers and gives it more control over its single largest raw-material cost. This matters more since China placed gallium and gallium compounds under export control in 2023. **Business model and revenue model.** **GaAs substrates (2–6 inch; LED, LD, RF grades):** Nature: Product sales, mostly by purchase order or framework supply agreement; Approximate weight: Core; the large majority of revenue **GaAs single crystals / ingots:** Nature: Product sales to wafer processors; Approximate weight: Secondary **Gallium metal (4N, 6N):** Nature: Product sales and internal captive supply; Approximate weight: Emerging (Yuanping plant mass production from April 2022) **GaAs substrate reclaim:** Nature: Service fee: epitaxial layers are stripped so substrates can be reused; Approximate weight: Small **Custom processing:** Nature: Custom specifications (diameter, finish, marking, packaging); Approximate weight: Embedded in product pricing The revenue model is entirely product and service based. There is no subscription or licensing income. The split between these streams is not publicly disclosed. **Value-chain position.** CCT sits upstream of epitaxial-wafer growers (MOCVD/MBE houses) and integrated device makers. Its inputs are gallium and arsenic (and boron oxide encapsulant, pBN crucibles, dopants). Its outputs go to epitaxy and chip makers such as San'an Optoelectronics, HC SemiTek, Changelight, Epistar and OSRAM, which make LED, laser, VCSEL, photodetector, RF and solar-cell devices. **Customer types.** LED chip makers (the largest group), laser and VCSEL chip makers, RF device makers, research institutes (Institute of Physics, Chinese Academy of Sciences) and state defence-electronics groups (China Electronics Technology Group, CETC). **End-markets served (company list).** LED lighting and displays (including LED TV, Mini/Micro LED), automotive lighting, lasers, 3D face recognition (VCSEL), automotive LiDAR and driver monitoring, VR glasses, Earth remote sensing, medical cosmetology lasers, thermometric indicators, 5G and RF data transmission, RF radar, military electronics, smartphones, optical and satellite communications, and thin-film solar cells.

Freiberger Compound Materials is one of the world's three dominant producers of gallium arsenide (GaAs) substrate wafers, the starting material for the radio-frequency power amplifiers in most of the world's smartphones and for the red and infrared LEDs, lasers and VCSELs used in optoelectronics. Its crystal-growth roots go back to 1957 in East Germany. Wacker's GaAs technology was transferred to Freiberg in 1990, and the Federmann family's Israeli holding company has owned FCM since 1995. The company grows crystals mainly by the Vertical Gradient Freeze (VGF) method and makes wafers up to 6 inches, and it produced the industry's first 8-inch semi-insulating VGF GaAs wafer in 2002. With Sumitomo Electric and AXT it supplies most of the world's GaAs substrates. It is the largest single industrial buyer of gallium, at about 10% of world output. Since 2022 it has added indium phosphide (InP) for AI-era optical interconnects and gallium nitride (GaN) substrates. In 2024 it bought PPM Pure Metals' high-purity arsenic business, integrating backward into a critical raw material. --- **What the company does.** FCM makes single-crystal III-V compound semiconductor substrates, which are polished wafers that customers use as the base for epitaxial growth (MOCVD and MBE) and device fabrication. The company describes itself as a leading global maker of compound semiconductor substrates for microelectronics and optoelectronics, with a reputation for extremely flat, ultra-clean wafers. Its current material set is GaAs, InP and GaN. The production chain runs in-house in four stages: synthesis of the polycrystalline compound from the elements, crystal growth, mechanical wafering (wire sawing, edge grinding, lapping), and polishing and cleaning to an "epi-ready" surface. The company says 87 measured characteristics specify each product. **Business model and revenue model.** FCM is almost entirely a product business. It sells physical wafers under specification agreements and supply contracts to epitaxy houses, integrated device manufacturers (IDMs) and foundries. It discloses no meaningful service, subscription or licensing revenue. Sales are priced per wafer, depending on diameter, doping, electrical properties and surface specification. Gallium metal is its largest single cost item, so contract pricing is exposed to the gallium price. Publicly funded R&D projects bring in some grant income, but this is not a revenue line. **Value-chain position.** **Raw materials (Ga, As, In, P):** Main participants: Chinese gallium refiners (more than 90% of supply), arsenic refiners, indium producers; FCM role: Buyer of gallium and indium; producer of high-purity arsenic through PPM High Purity Metals since 2024 **Polycrystal synthesis:** Main participants: Substrate makers (captive); FCM role: In-house **Single-crystal growth (VGF, formerly LEC; HVPE for GaN):** Main participants: Sumitomo Electric, FCM, AXT/Tongmei, JX Advanced Metals and others; FCM role: Core competence **Wafering, polishing, cleaning:** Main participants: Substrate makers; FCM role: In-house **Epitaxy:** Main participants: IQE, IntelliEPI, VPEC, LandMark, captive IDM epi; FCM role: Customer segment **Device fabrication:** Main participants: Qorvo, Skyworks, Broadcom (Avago), WIN Semiconductors, Coherent, ams OSRAM, Lumentum and others; FCM role: End customers **End products:** Main participants: Smartphones, Wi-Fi, base stations, data-centre transceivers, LiDAR, LEDs; FCM role: End markets **Customer types.** FCM serves (i) epitaxial wafer foundries, (ii) GaAs RF IDMs and foundries making heterojunction bipolar transistors (HBTs) and pHEMTs for power amplifiers and switches, (iii) optoelectronic device makers producing LEDs, laser diodes, VCSELs and photodetectors, and (iv) research institutes and universities. FCM does not name its customers. In July 2023 the CEO said the world's leading power-amplifier makers are based in the United States, which points to US RF IDMs as a core customer group. **End markets.** **Mobile and wireless RF:** Material: Semi-insulating GaAs; Device types: HBT and pHEMT power amplifiers, switches, LNAs; Demand driver: Smartphone units, RF content per phone, Wi-Fi 6/7 **Optoelectronics and sensing:** Material: Semi-conducting GaAs; Device types: Red/IR LEDs, laser diodes, VCSELs, sensors; Demand driver: 3D sensing, LiDAR, displays, industrial lasers **Optical communications and AI data centres:** Material: InP; Device types: DFB/EML lasers, photodiodes, PICs; Demand driver: 800G/1.6T transceivers, AI cluster interconnect **High-frequency electronics, defence and space:** Material: Semi-insulating InP, GaAs; Device types: HEMTs, HBTs, mmWave ICs; Demand driver: Radar, satellite links, sub-THz research **Power and optoelectronics:** Material: GaN; Device types: Laser diodes, high-power devices; Demand driver: Blue/green lasers, vertical GaN power devices **Automotive:** Material: GaAs, InP; Device types: Sensors, LiDAR emitters, radar; Demand driver: ADAS, in-cabin sensing **Company's own characterisation.** FCM calls itself a technology leader in III-V substrate wafers made from GaAs, InP and GaN, and a world-leading supplier with more than 50 years of experience in semiconductor materials. **Independent characterisation.** FCM is a single-site, deeply vertically integrated specialist materials manufacturer. Its market position is outsized relative to its size: revenue is roughly EUR 70–100 million, yet it holds a majority share of the GaAs wafers used in smartphone power amplifiers. Its competitive moat rests on process know-how in large-diameter, low-defect VGF growth and on more than 25 years of qualification with demanding RF customers, not on scale. Strategically, it is now Europe's main non-Chinese source of compound-semiconductor substrates. That status has grown in political and commercial value since China began licensing gallium exports in August 2023. The company is broadening its portfolio: it is moving from a mature GaAs RF franchise, where GaN-on-SiC and silicon technologies are encroaching, toward InP, which is driven by AI data-centre optics and grows faster.

Irresistible Materials is a UK-based, venture- and strategically-backed developer of next-generation photoresists for extreme ultraviolet (EUV) lithography, the patterning step that defines the smallest features on leading-edge logic and memory chips. Its core asset is the patented Multi-Trigger Resist (MTR™), a metal-free, small-molecule negative-tone resist chemistry that the company says has molecules up to ten times smaller than conventional polymer resists, and that uses a multi-step activation mechanism to limit acid diffusion and the stochastic blur that limits conventional chemically amplified resists (CARs). MTR is positioned as a third resist platform alongside CARs and metal-oxide resists (MORs), aimed at both today's 0.33-NA EUV scanners and ASML's 0.55 high-NA tools. In October 2025 Tokyo Ohka Kogyo (TOK), one of the three suppliers that dominate the EUV resist market, became its controlling-interest shareholder and joint development partner. In June 2026 IM sold its LiquidCarbon™ spin-on-carbon patents to Nano-C so that it could focus only on MTR. The company is pre-revenue at scale, has around ten employees, and is preparing to sample customers and scale up manufacturing. **What the company does.** Irresistible Materials designs, formulates and optimises photoresist chemistries for EUV lithography at 13.5 nm wavelength. A photoresist is the light-sensitive film spun onto a wafer that records the pattern projected by the scanner. Resist performance governs three linked variables: resolution (how small a feature can be printed), line-edge and line-width roughness (LER/LWR), and sensitivity (the dose needed, which drives scanner throughput). At EUV wavelengths these three trade off against each other because of photon shot noise and resist chemistry. IM's whole strategy rests on the claim that its MTR mechanism loosens that trade-off. **Company's own description.** In its February 2026 joint release with TOK, IM describes itself as a pioneering electronic materials technology company that develops advanced photoresists for next-generation EUV lithography. It says its patented MTR offers better imaging performance for low-NA and high-NA EUV than competing solutions on several criteria, and that integrated device manufacturer (IDM) and foundry customers can get higher yields and lower cost of ownership (CoO) for logic and memory devices. The website frames the mission as developing resists that behave predictably under EUV exposure, which improves throughput, CoO and yield, and as moving technologies from research into manufacturing alongside semiconductor customers and partners. **Independent characterisation.** IM is a deep-technology IP and formulation company that has not yet reached commercial scale. For more than a decade it has developed a non-polymeric (molecular) resist family and has tested it on industry-standard tools, including ASML NXE scanners through imec, the Paul Scherrer Institute (PSI) EUV interference lithography beamline and the Berkeley micro-exposure tool (MET). Manufacturing has always been outsourced: first to Nano-C, Inc. (Westwood, Massachusetts), and since 2025–26 increasingly through TOK's ISO-certified photoresist manufacturing and quality systems. Commercially it is at the qualification and sampling stage. Chipmakers spend several years qualifying resists layer by layer and node by node before volume adoption. **Business and revenue model.** Since its earliest public statements, the model has changed in three stages: **2014–2017:** Stated model: IP licensor to established resist suppliers, while behaving like a resist supplier to win scanner time and customer evaluations; Evidence: Co-founder David Ure told EE Times Europe (2017) that IM's primary model would be licensing IP to resist suppliers **2015–2026 (spin-on carbon):** Stated model: Licensing and distribution through a channel partner, with material made by Nano-C; Evidence: 2015 licence with MicroChem Corp. for sale and distribution of IM spin-on-carbon materials **2025 onward:** Stated model: Co-development and commercialisation with a strategic resist major (TOK), with TOK adding MTR to its resist portfolio and manufacturing it for high-volume manufacturing (HVM); Evidence: February 2026 IM–TOK joint release The revenue mix between product sales, development fees, licensing royalties and grants is not publicly disclosed. As a small company, IM files abridged accounts that do not include a profit and loss account, and turnover is unreported. Historically, non-dilutive income has included UK government grants (Technology Strategy Board / Innovate UK and the UKRI grant programme). **Value chain position.** IM sits upstream in the lithography materials chain: **Fine chemical / precursor synthesis:** Participants: Specialty chemical makers (e.g., Nano-C for fullerene and molecular components); IM role: Specifies and sources components; resist has four or five elements (CEO interview, March 2025) **Resist formulation and optimisation:** Participants: TOK, JSR/Inpria, Shin-Etsu, Fujifilm, Sumitomo Chemical, Dongjin Semichem, DuPont, IM; IM role: Core activity: custom formulations per layer and customer **Resist manufacturing and QC at volume:** Participants: Resist majors with ISO-certified plants; IM role: Through TOK (from 2025–26) and Nano-C **Process integration and evaluation:** Participants: imec, ASML, Albany NanoTech EUV Accelerator, PSI, Berkeley Lab; IM role: Testing partner relationships **Device manufacturing:** Participants: Logic foundries, IDMs, DRAM makers; IM role: Target end customers **Customer types.** The targets are leading-edge IDMs and foundries running EUV lithography for logic and memory. In 2018 eeNews Europe reported that IM was supplying Intel, Samsung and GlobalFoundries, and had dealings with TSMC, for evaluation material. The company has not named any current production customer. In March 2025 the CEO said chipmakers were going through material qualification and that IM expected engagement opportunities over 2025–2026. **End markets served.** These are advanced logic (3 nm-class and below, A14/A10 nodes), DRAM moving towards EUV and high-NA, and, through spin-on carbon historically, MEMS, 3D chip structures and hard-mask applications. Demand comes ultimately from AI accelerators, data-centre CPUs, HBM/DRAM and premium mobile processors.

SP Samhwa is one of South Korea's oldest integrated paint makers and has long ranked third in the domestic coatings market, behind KCC and Noroo. Founded in Busan in 1946, it makes architectural, industrial, automotive-refinish, powder, coil (PCM), fire-retardant, flooring and waterproofing coatings. It runs two main domestic plants, in Ansan and Gongju, and subsidiaries in China, Vietnam, Malaysia and India. Consolidated revenue has been roughly flat at about KRW 620–650 billion since 2021. Margins are thin, held down by the weak Korean construction market. The company is now trying to reposition itself as a "comprehensive chemical solutions" company. It renamed itself in March 2026 and is commercialising semiconductor packaging materials: it supplies melt master batch (MMB) to Samsung SDI and mass-produces its own epoxy molding compounds (EMC). It is also developing secondary-battery additives and thermal-runaway coatings, energy-infrastructure coatings and defence stealth/EMI materials. The founding Kim family moved to a third-generation owner-CEO after Chairman Kim Jang-yeon died in December 2025. The co-founding Yoon family remains a large shareholder, and Japan's Chugoku Marine Paints is a strategic shareholder. --- ### What the company does SP Samhwa formulates, manufactures and sells paints, coatings and related chemical products. Its own description, in its 2026 Sustainability Report covering fiscal 2025, calls it a leading Korean integrated coatings company. It makes architectural, industrial and automotive-refinish coatings, and its traditional stronghold, architectural coatings, has been extended into interior and fire-retardant coatings. The company now groups its products into two solution families: **Architecture & Living Solutions:** waterproofing (Bangsu Ace), fire-retardant and intumescent coatings (FLAMECHECK), interior paints (Aisaenggak, Ailux), epoxy flooring (EPOCOAT) and sports/parking-deck coatings (Urecoat). **Industrial & Advanced Materials Solutions:** BIPV (building-integrated photovoltaic) coatings, marine and offshore-plant coatings certified to NORSOK M-501, phase-change-material (PCM) non-combustible paint, automotive refinish (RM, Carocle), thermal-control materials, battery additives and semiconductor EMC. ### Business model and revenue model The revenue model is almost entirely product sales. There are no material subscription, licensing or service revenues. Value is created through formulation know-how (resin synthesis, pigment dispersion, additive chemistry, cure control) applied at scale in batch production. Sales reach the market through three channels: 1. **Dealer/agency network** for architectural and retail coatings, supported by regional business centres across Korea. 2. **Direct B2B supply** to industrial OEMs: electronics and plastics coaters, automotive refinish shops, steel coil coaters, construction contractors, public institutions, and now semiconductor packaging-material makers. 3. **Overseas subsidiaries** that serve local OEMs, chiefly coatings for plastic parts used in consumer electronics and automotive, in China, Vietnam, Malaysia and India. A small IT-services segment (subsidiary SM2 Networks) contributes around 3% of consolidated revenue. Logistics (Samhwa Logitech), real-estate and other subsidiaries sit in an "other" segment that has been loss-making. ### Value-chain position SP Samhwa sits in the middle of the chemical value chain. It buys petrochemical intermediates (epoxy, acrylic, alkyd and urethane resins and their monomers), titanium dioxide and other pigments, solvents and additives. It synthesises some resins in-house and formulates finished coatings. In semiconductor materials it is an upstream formulator. MMB is a pre-reacted resin/additive intermediate that Samsung SDI compounds into EMC. SP Samhwa's own EMC is a finished encapsulant sold to outsourced assembly and test (OSAT) houses and to integrated device makers' packaging lines, ultimately for mobile application processors. ### Customer types and end-markets | End-market | Products | Demand driver | |---|---|---| | Residential and commercial construction (new build and repaint) | Architectural paints, waterproofing, flooring, fire-retardant | Housing starts, apartment repainting cycles, fire-safety regulation | | Industrial / heavy-duty protection | Anticorrosive, offshore-plant, intumescent, powder coatings | Plant, energy and offshore-wind capex | | Steel coil (PCM) | Coil coatings | Construction panels and appliances | | Automotive aftermarket | Refinish systems including UV-curable refinish | Vehicle parc, collision repair | | Consumer electronics and automotive plastics | Plastic coatings (China, Vietnam, India subsidiaries) | Handset, appliance and auto-parts output | | Semiconductors | MMB, EMC | Mobile AP and memory packaging volumes | | Secondary batteries / ESS | Electrolyte additives, thermal-runaway barrier coatings | EV and ESS cell output | | Defence | Stealth and EMI-shielding materials (via the Flyer partnership) | Military drone programmes | The 2026 Sustainability Report lists its customers as final consumers, corporate clients, public institutions, construction companies, automotive and electronics manufacturers, and dealers/agents.

Its operating margin has stayed between about 0.1% and 4.1% over five years, and it is attempting a portfolio pivot from a modest earnings base. Its competitive moats in paint are its brands, the dealer network and long-standing B2B qualifications. These are durable but grow slowly. The semiconductor packaging business is strategically significant but immaterial to group revenue today. By the company's own segment disclosures, paint and chemical products still account for substantially all revenue and operating profit. The investment case therefore rests on three things: a cyclical recovery in domestic construction coatings, margin repair from the specialty mix (fire-retardant coatings, UV refinish, overseas projects), and option value in electronic and energy materials.

HHCK is China's largest maker of epoxy molding compounds (EMC), the thermoset plastic that encapsulates almost every plastic-packaged semiconductor. In October 2025 it bought Hengsuo Huawei, its larger domestic rival and the former Henkel/Hysol EMC operation in Lianyungang, which has been making EMC since 1983. Together they ship more than 25,000 tonnes of semiconductor EMC a year. On management's account, that makes the group the domestic leader and the world's second-largest EMC shipper by volume, behind Sumitomo Bakelite and ahead of Resonac and the other Japanese and Korean suppliers. The portfolio spans commodity grades for discretes (DO, SMX, TO, DIP), high-performance grades for SOT, SOP, QFP and automotive power devices, and advanced-packaging materials: QFN/BGA EMC, granular molding compound, liquid molding compound, flip-chip underfill and HBM-oriented high-thermal-conductivity grades. Its customers are China's top OSATs (JCET, Tongfu, Huatian) and global IDMs (Infineon, onsemi, Nexperia, STMicroelectronics, Texas Instruments). The investment case rests on import substitution in high-end EMC, AI-driven advanced-packaging demand, and automotive/SiC power modules. These are offset by roughly RMB 1 billion of acquisition goodwill and a still-small overseas business. **Name clarification.** "Huawei" in Hengsuo Huawei (衡所华威) comes from the historical Lianyungang "Huawei Electronics" EMC business. It is not part of Huawei Technologies. Separately, Huawei's investment arm, Hubble Technology Investment, was a pre-IPO shareholder in HHCK. Its stake was below the top-ten threshold of 0.92% at 31 December 2025. ### Company description In its 2025 annual report, HHCK describes itself as a research-led high-tech enterprise and a national "Specialised and Sophisticated Little Giant" (专精特新"小巨人"). It says it focuses on the R&D, industrialisation and sale of semiconductor packaging materials. Its main products are epoxy molding compounds and electronic adhesives. They are used in semiconductor packaging, structural-component packaging and board-level assembly. The company says its core technology system gives it a product range covering both traditional and advanced packaging. EMC is made from an epoxy resin base with high-performance phenolic resin as the hardener, a large proportion of silica (fused or spherical silicon micro-powder) as filler, and a package of additives: coupling agents, flame retardants, stress modifiers, ion scavengers, release agents, carbon black and accelerators. It protects the die from moisture, heat, contamination and mechanical shock. It also provides thermal conduction, electrical insulation, voltage withstand and mechanical support. Plastic encapsulation accounts for more than 95% of integrated-circuit packaging worldwide, which makes EMC a high-volume consumable for every back-end assembly line. ### Business model | Dimension | Model | |---|---| | Revenue model | Almost entirely product sales of formulated materials, priced per kilogram or tonne by grade.

Downstream customers are outsourced assembly and test companies (OSATs) and integrated device manufacturers (IDMs). End-markets are consumer electronics, industrial and power electronics, automotive (including SiC/IGBT power modules), photovoltaic and new-energy equipment, communications and data-centre/AI hardware, and memory. ### Customer types and end-markets | Customer type | Named customers | |---|---| | Chinese OSATs | JCET (长电科技), Tongfu Microelectronics (通富微电), Huatian Technology (华天科技) | | Chinese discrete and power device makers | Yinhe Microelectronics (银河微电), Yangjie Technology (扬杰科技), Silan Microelectronics (士兰微), Lipuxin | | Global IDMs (largely through Hengsuo Huawei) | Infineon, onsemi, Nexperia, STMicroelectronics, Texas Instruments | | Power-module makers | A global top-five power-device maker uses Hengsuo's GR750X1 in 1200 V SiC modules | **Chinese OSATs:** Named customers: JCET (长电科技), Tongfu Microelectronics (通富微电), Huatian Technology (华天科技) **Chinese discrete and power device makers:** Named customers: Yinhe Microelectronics (银河微电), Yangjie Technology (扬杰科技), Silan Microelectronics (士兰微), Lipuxin **Global IDMs (largely through Hengsuo Huawei):** Named customers: Infineon, onsemi, Nexperia, STMicroelectronics, Texas Instruments **Power-module makers:** Named customers: A global top-five power-device maker uses Hengsuo's GR750X1 in 1200 V SiC modules ### Independent characterisation Before the merger, HHCK was a fast-growing but sub-scale domestic challenger. About 93–95% of its revenue came from EMC. It was strongest in commodity discrete packages (DO/SMX/bridge, TO, DIP) and was trying to break into QFN/BGA and fan-out packaging. Buying Hengsuo Huawei changed the company's character. It gained a 40-year-old business with the Hysol brand, over 100 qualified grades, accounts with multinational IDMs, a leading domestic position in automotive-grade and capacitor EMC, and small subsidiaries in South Korea and Malaysia. The combined group is now mainly a story about scale and import substitution, with an option on advanced packaging. In the first half of 2026, Hengsuo Huawei generated more than half of consolidated revenue.

ENF Technology is a Korean maker of wet process chemicals for semiconductor and display fabs. Its core products are etchants, thinners, strippers, developers and cleaning solutions. It also makes fine chemicals, including photoresist monomers, polymers and photo-acid generators; colour pastes for colour resists; and, through its UBmaterials subsidiary, CMP slurries. About two-thirds of FY2025 revenue came from semiconductors and about one-third from displays. Its main customers are Korea's memory and panel makers. ENF has four Korean production bases (Ulsan, Asan, Cheonan and Giheung), a display-chemicals plant in Guangzhou, China, and a plant in Kyle, Texas, that supplies Samsung's Austin and Taylor fabs. Since the 2019 Japanese export controls, the company has worked to make hydrofluoric acid (HF) in Korea. Consolidating FEM Technology in 2026 completed an HF chain that runs from raw material to finished etchant. In June 2026 ENF began supplying HF to SK hynix DRAM lines. The shares trade at a clear discount to Korean electronic-materials peers. **What the company does.** ENF Technology develops, makes and sells high-purity speciality chemicals used in semiconductor and flat-panel display manufacturing. Its own description is a company "engaged in research, development, manufacture and sale of speciality chemicals for semiconductor and display manufacturing processes." For accounting purposes it reports one segment, electronic materials (전자재료). Management analyses revenue by end-market: semiconductor, display and other. **Business model.** ENF sells products, not services. Revenue comes from repeat shipments of consumable chemicals that are qualified into specific process steps at customer fabs. These materials are used up continuously, so volumes follow customer wafer starts and panel output rather than customer capital spending. Once a chemical is qualified for a process step, switching suppliers means a long requalification, which makes customers sticky. The model has no material subscription, licensing or service revenue. ENF also runs a thinner-recycling business, which recovers and repurifies used solvent for customers. This deepens its ties to customer fabs and gives it a lower-cost feedstock loop. **Revenue mix by end-market (FY2025, company IR):** **Semiconductor:** Revenue FY2025 (KRW bn): 432.8; Share of total (%): 64.5; YoY growth (%): 14 **Display:** Revenue FY2025 (KRW bn): 228.0; Share of total (%): 34.0; YoY growth (%): 8 **Other (fine chemicals, new materials):** Revenue FY2025 (KRW bn): 10.1; Share of total (%): 1.5 **Total:** Revenue FY2025 (KRW bn): 670.9; Share of total (%): 100.0; YoY growth (%): 15.2 **Position in the value chain.** ENF sits between commodity chemical producers and device makers. It buys propylene oxide and propylene derivatives (thinner inputs), anhydrous hydrogen fluoride, phosphoric acid, hydrogen peroxide and organic acids. It purifies, formulates and blends these into fab-grade solutions with impurities at parts-per-trillion levels. It then delivers them by bulk tanker or in ISO containers to customer fabs, often with on-site supply management. Upstream integration is growing. FEM Technology makes HF and buffered oxide etchant (BOE) at Asan. The Cheonan plant has its own HF production system. The Ulsan plant synthesises photoresist raw materials. **Customer types and end-markets.** - Memory makers: Samsung Electronics and SK hynix. Demand is tied to DRAM, HBM and NAND output in Korea. - Foundry and logic: Samsung Electronics' Austin and Taylor fabs in Texas, supplied from Kyle. - Display panel makers: Korean OLED makers and Chinese panel makers served from Guangzhou. Historically LG Display was a major customer. - Photoresist makers: buyers of ENF's PR monomers, polymers and photo-acid generators. - Colour-resist makers: buyers of its colour pastes for notebook, large-TV and WOLED panels. **Independent characterisation.** ENF has moved from a display-led thinner supplier with low entry barriers to a semiconductor-led process-chemical house. Semiconductors were about 55% of revenue in mid-2020 and 64.5% in FY2025. The strategic thesis now rests on three things. The first is HF-based etchant vertical integration, where Japanese suppliers have long dominated. The second is entry into high-selectivity phosphoric-acid nitride etchants. The third is a US manufacturing footprint that matches Samsung's Texas expansion. ENF is profitable and generates cash, but margins are modest for its sector. The operating margin was 11.6% in FY2025, against a peer median near 17.6%. This reflects the large share of formulated solvents (thinners and strippers), where raw materials make up most of the cost. Pricing power is limited by concentrated customers.

Jianghua Micro-electronic Materials (JHM) was the first specialist wet electronic chemicals company to list in China. It makes ultra-clean high-purity reagents (acids, bases, solvents and oxidisers) and photoresist ancillary reagents (developers, strippers, etchants and cleaning solutions). These are used for cleaning, lithography, developing, etching and stripping in the manufacture of semiconductor wafers, flat-panel displays and crystalline-silicon solar cells. The product range covers SEMI grades G2 to G5. Production runs at three bases: Jiangyin (Jiangsu), Zhenjiang (Jiangsu) and Meishan (Sichuan). FY2025 revenue was CNY 1.234 billion, and semiconductors supplied 58.7% of core-business sales. The company is mid-sized in a fragmented domestic market of 50-plus producers. Its rivals for high-end 12-inch fab business include Japanese, US, European and Korean incumbents and fast-growing Chinese peers such as Hubei Xingfu Electronic Materials. In August 2026 control passed from Zibo municipal state capital to Shanghai's chemical state-owned group, Shanghai Huayi. JHM is now Shanghai SASAC's listed platform for semiconductor wet chemicals. --- ### What the company does JHM develops, produces and sells wet electronic chemicals. These are liquid reagents whose main component is ultra-pure, and whose metal-ion and particle impurities are controlled to parts-per-billion or parts-per-trillion levels. Customers use them in wet process steps: **Cleaning:** Wafer and glass-substrate cleaning before and after deposition, etching and CMP. **Lithography and developing:** Developers such as TMAH-based solutions, edge-bead removers and thinners. **Etching:** Metal etchants (for example, aluminium etchant for integrated circuits), oxide etchants and mixed acids. **Stripping:** Photoresist strippers and post-etch residue removers. **Doping and texturing:** Mainly in crystalline-silicon solar cells. The 2025 annual report describes the main business as "research, development, production and sale of ultra-clean high-purity reagents, photoresist ancillary reagents and other wet electronic chemicals", used chiefly in display panels, semiconductor chips and solar cells for cleaning, lithography, developing, etching and similar processes. The company calls itself "China's first listed specialist wet electronic chemicals enterprise" and says its products cover SEMI grades G2 to G5 in full. ### Business and revenue model | Dimension | Description | |---|---| | Revenue type | Nearly all product sales. Main-business revenue was CNY 1,210.2 million of CNY 1,233.8 million total revenue in FY2025. Other operating income (materials, scrap and services) was about CNY 23.6 million. There is no subscription or licensing income. | | Production model | "Produce according to sales, purchase according to production". Products are made to customer specifications and qualified per fab or panel line. | | Sales model | 100% direct sales to end users. FY2024 direct-sales revenue was CNY 1,069.6 million at a 25.62% gross margin. | | Pricing | Prices are set per tonne, by product and grade. Over 9M FY2026 the average selling price was CNY 6,672/t for ultra-clean reagents (−0.35% YoY) and CNY 10,997/t for photoresist ancillary reagents (+1.75% YoY). | | Customer concentration | The top five customers took 42.14% of FY2025 sales, with no related parties.

It buys industrial-grade or first-grade inputs: sulphur trioxide (for sulphuric acid), phosphoric acid, hydrofluoric acid, isopropanol, liquid ammonia, hydrogen peroxide and glycol ethers. It then purifies, blends, filters, packages and tests them to electronic grade. Its value added lies in: 1. purification technology (rectification, sub-boiling distillation, ion exchange and membrane filtration); 2. ultra-trace analysis (ICP-MS and particle counting); 3. clean packaging and container handling; and 4. formulation know-how for functional chemicals such as etchants, strippers and developers. Customer qualification cycles for 12-inch logic and memory fabs typically run 12 to 36 months. This creates switching costs once a supplier is qualified. ### Customer types and end markets - **Semiconductors (wafer fabs, silicon wafers, advanced packaging, third-generation semiconductors, LED)** — FY2025 revenue (CNY M): 710.8; Share of main business: 58.73%; Representative customers named by the company: Hua Hong Group, ChangXin Memory (CXMT), TCL Zhonghuan, JCET - **Flat-panel displays (TFT-LCD, OLED, colour filter, touch panel)** — FY2025 revenue (CNY M): 455.3; Share of main business: 37.62%; Representative customers named by the company: BOE, CSOT (TCL China Star) **Crystalline-silicon solar cells:** FY2025 revenue (CNY M): 44.1; Share of main business: 3.65%; Representative customers named by the company: Solar cell makers (not named) ### Independent characterisation JHM started as a display-panel and solar chemicals supplier. It has repositioned toward semiconductors over the past five years. Semiconductor revenue rose from about CNY 499 million in FY2023 to CNY 711 million in FY2025, and 8–12-inch wafer-fab products grew 39.7% in FY2025 to CNY 381 million. The strategic asset is the Zhenjiang G5 base, built for 12-inch advanced-node customers. Its sales doubled in FY2025 to CNY 144 million, but it remains loss-making. The core Jiangyin base is the profit engine but is a mature, display-heavy operation. Gross margins of 24–28% are typical for a commodity-adjacent specialty chemical. Profits are therefore sensitive to raw-material spikes, as the 127% rise in sulphur trioxide prices in 2026 showed. They are also sensitive to depreciation from new capacity. The equity story is now driven largely by Shanghai SASAC's ownership and the expected integration into Shanghai's integrated-circuit cluster.

Yingde Gases is China's largest independent (non-captive, non-multinational) industrial gas company and one of Asia's largest air-separation operators. Founded in Hunan in 2001, it built its franchise on long-term on-site oxygen, nitrogen and argon supply to steel, non-ferrous metals and chemical complexes, backed by take-or-pay contracts. It then extended into bulk liquid, MiniBulk, cylinder, rare and specialty gases and in-house cryogenic engineering through Yingde Engineering. After eight years under PAG, including the 2021 merger with Baosteel Gases and an abandoned Hong Kong IPO, control passed in January 2025 to a Hangzhou-led state-capital and insurance consortium in one of China's largest private-equity exits. PAG kept a minority stake and the clean-energy (syngas/hydrogen/methanol) business. In semiconductor supply chains, Yingde's role is mainly bulk atmospheric gases: nitrogen, oxygen and argon, plus hydrogen and high-purity oxygen for electronics, photovoltaic and new-energy manufacturers. Its competitors in ultra-high-purity electronic bulk gases are Linde, Air Liquide, Air Products and Guanggang Gases. Its overseas platform, NovaAir, operates in Malaysia, Thailand and India. --- ### What the company does Yingde Gases designs, builds, owns, operates and maintains air separation units (ASUs) and related gas-production facilities. It sells the output in three main ways: 1. **On-site supply.** Gas goes by pipeline from plants located at or next to large industrial customers, under long-term supply contracts with minimum take-or-pay volumes and cost pass-through clauses. 2. **Merchant (liquid) supply.** Liquid oxygen, nitrogen, argon and carbon dioxide are delivered by cryogenic tanker to distributors and industrial users. The liquid comes from the spare capacity of on-site plants plus dedicated liquid plants. 3. **Packaged, MiniBulk, rare and specialty gases.** These cover cylinders and small-bulk installations, including the "盈德钢瓶气" cylinder business, plus rare gases and electronic specialty gases. Alongside these, Yingde Engineering designs and manufactures cryogenic equipment, including large ASUs, skid-mounted liquid ASUs, nitrogen generators and VPSA (vacuum pressure swing adsorption) oxygen systems, for internal projects and for third-party customers. The company's current self-description lists six business lines: on-site gas supply, liquid gas supply, rare and specialty gases, Yingde Engineering, overseas business, and logistics and transportation. It also offers application solutions under its own brands: 焊德宝® (welding), 渔德宝® (aquaculture oxygenation) and 鲜德宝® (food quick-freezing). Products listed include liquid oxygen, liquid nitrogen, liquid argon, carbon dioxide, medical oxygen, hydrogen, methanol, rare gases, electronic specialty gases and cylinder gas. In its overseas communications (October 2026), Yingde describes itself as focused on "on-site gas supply, bulk liquid, MiniBulk, packaged gases, rare and specialty gases, and Yingde Engineering". It says it supplies oxygen, nitrogen and argon by pipeline, tank and cylinder to metallurgy, chemical, electronics, semiconductor, photovoltaic, food, medical and healthcare, new materials, energy and environmental protection industries in China and Southeast Asia. ### Business and revenue model | Revenue model element | Description | |---|---| | Product sales under long-term contracts | On-site gas sold under multi-year contracts (typically 15+ years in the industry) with minimum take-or-pay volumes and electricity cost pass-through.

Volatile, follows industrial activity and liquid price cycles. 14.7% of revenue in FY2020 **Packaged / MiniBulk gas:** Description: Cylinder and small-bulk sales, including the online channel "Yingde Mall" (shop.yingde.com) **Equipment and engineering:** Description: Sales of ASUs, nitrogen generators and VPSA units by Yingde Engineering to third parties, such as Wanhua Chemical, Yimen Copper and Taishan Steel (2025–2026) **Clean energy (historic, now carved out):** Description: Hydrogen, syngas, liquid ammonia and methanol from coal-gasification "gasification island" projects using Tsinghua-furnace technology. 19.7% of revenue in FY2020. Separated in 2024 and retained by PAG at the January 2025 sale The model is overwhelmingly product-based (gas sold per unit volume), with an equipment/engineering component. No subscription or licensing revenue is disclosed. ### Value-chain position Yingde sits in the middle of the industrial-gas value chain: **Upstream inputs:** electricity (the main variable cost of air separation), equipment (compressors, cold boxes, turbo-expanders, some built in-house) and coal or coke-oven gas for syngas and hydrogen projects. **Own operations:** production (ASUs, nitrogen generators, VPSA units, hydrogen recovery), storage, distribution (a tanker fleet that once ran more than 500 vehicles a day) and engineering. **Downstream customers:** steelmakers, non-ferrous smelters, coal-chemical and petrochemical complexes, new-energy material producers (lithium iron phosphate, sodium-ion, solar), electronics/semiconductor/photovoltaic manufacturers, food processors and hospitals. ### Customer types and end-markets | End-market | Role of Yingde gases | Examples (publicly announced) | |---|---|---| | Iron & steel | Oxygen for blast furnace/BOF, nitrogen and argon for inerting and refining | Taishan Steel (40,000 Nm³/h ASU agreement, 2026); Alliance Steel, Kuantan, Malaysia (three 20,000 Nm³/h ASUs) | | Non-ferrous metals | Oxygen enrichment for smelting | Jinchuan Group (intelligent ASU, 2025); Yimen Copper (VPSA oxygen system, 2026) | | Chemicals / coal chemicals | Oxygen and nitrogen for gasification and oxidation; pipeline nitrogen | Wanhua Chemical Fujian (60,000 Nm³/h ASU, 2025); Haixing Chemical (pipeline nitrogen, 2026); Gansu Juhua (ASU start-up) | | New energy materials | High-purity nitrogen for lithium iron phosphate calcination; nitrogen for battery materials | Wanhua Chemical LFP project (large nitrogen generation equipment, 2026); a large nitrogen plant for a new-energy customer | | Electronics, semiconductor & photovoltaic | Bulk nitrogen, oxygen, argon and hydrogen; high-purity oxygen for solar cell processes | Malaysian KUL ASU built to switch to high-purity oxygen for solar cell manufacturing | | Clean energy / tail-gas recovery | Coke-oven gas recovery and co-production | Qujing, Yunnan (strategic cooperation, 2026); Anyang clean gas demonstration project (large ASU) | | Food, aquaculture, healthcare | Liquid nitrogen for freezing, oxygen for aquaculture, medical oxygen | 鲜德宝®, 渔德宝® application brands | **Iron & steel:** Role of Yingde gases: Oxygen for blast furnace/BOF, nitrogen and argon for inerting and refining; Examples (publicly announced): Taishan Steel (40,000 Nm³/h ASU agreement, 2026); Alliance Steel, Kuantan, Malaysia (three 20,000 Nm³/h ASUs) **Non-ferrous metals:** Role of Yingde gases: Oxygen enrichment for smelting; Examples (publicly announced): Jinchuan Group (intelligent ASU, 2025); Yimen Copper (VPSA oxygen system, 2026) **Chemicals / coal chemicals:** Role of Yingde gases: Oxygen and nitrogen for gasification and oxidation; pipeline nitrogen; Examples (publicly announced): Wanhua Chemical Fujian (60,000 Nm³/h ASU, 2025); Haixing Chemical (pipeline nitrogen, 2026); Gansu Juhua (ASU start-up) **New energy materials:** Role of Yingde gases: High-purity nitrogen for lithium iron phosphate calcination; nitrogen for battery materials; Examples (publicly announced): Wanhua Chemical LFP project (large nitrogen generation equipment, 2026); a large nitrogen plant for a new-energy customer **Electronics, semiconductor & photovoltaic:** Role of Yingde gases: Bulk nitrogen, oxygen, argon and hydrogen; high-purity oxygen for solar cell processes; Examples (publicly announced): Malaysian KUL ASU built to switch to high-purity oxygen for solar cell manufacturing **Clean energy / tail-gas recovery:** Role of Yingde gases: Coke-oven gas recovery and co-production; Examples (publicly announced): Qujing, Yunnan (strategic cooperation, 2026); Anyang clean gas demonstration project (large ASU) **Food, aquaculture, healthcare:** Role of Yingde gases: Liquid nitrogen for freezing, oxygen for aquaculture, medical oxygen; Examples (publicly announced): 鲜德宝®, 渔德宝® application brands ### Independent characterisation Yingde is best understood as a capital-intensive, contract-backed infrastructure operator whose earnings come from (a) a long-dated portfolio of on-site ASU contracts with heavy-industry customers and (b) a cyclical merchant liquid business that amplifies swings in industrial activity and liquid gas prices. Its semiconductor relevance is real but secondary. Yingde is a large-scale producer of the atmospheric gases (nitrogen, oxygen, argon) and hydrogen that fabs use as bulk inputs. However, the ultra-high-purity (ppb-level) electronic bulk-gas supply to Chinese front-end fabs is concentrated among Linde, Air Liquide, Air Products and Guanggang Gases, and Yingde is not a leading supplier there. Its electronics exposure is mainly merchant liquid nitrogen/argon, photovoltaic and new-energy customers, and specialty/rare gases. The January 2025 ownership change replaced a financial sponsor focused on exit with patient domestic capital (local state funds and insurers). This lowers refinancing and exit pressure but leaves open whether Yingde will eventually be combined with Hangyang, which is also controlled by Hangzhou Capital.

Jinhong Gas is China's largest privately owned integrated industrial-gas company. Its sales have ranked first among private gas companies in the China Industrial Gases Industry Association statistics for many years. It sells three things. The first is bulk gases (oxygen, nitrogen, argon, carbon dioxide, acetylene), delivered in cylinders and as liquid through a dense retail network centred on the Yangtze River Delta. The second is specialty and electronic gases: 7N ultra-pure ammonia, high-purity nitrous oxide, high-purity hydrogen, high-purity CO₂, electronic-grade TEOS, a growing fluorinated-etchant range, and helium. The third is long-term on-site supply: air-separation units for steel and chemical customers, and electronic bulk carrier-gas plants for semiconductor and display fabs. The company is moving from cylinder-and-tanker retail towards a hybrid model. That model combines retail density with take-or-pay on-site contracts, a contracted backlog that reached about CNY 8.8 billion in total value, and a vertically integrated helium supply chain. Since 2024 the shift has squeezed earnings through depreciation, interest and acquisition impairments. In return it has built a contracted, more cyclically resilient revenue base. In the global helium shock of 2026 it also gave the company a strategically valuable domestic helium supply position. --- **What the company does.** Jinhong Gas researches, produces, sells and services industrial gases. Its IPO prospectus already described a portfolio of more than 100 gas types across specialty gases, bulk gases and natural gas, sold to customers in electronics and semiconductors, photovoltaics, LED and display, optical fibre, healthcare, steel, chemicals, new energy, food and beverage, and general manufacturing. Management describes the company as a "comprehensive gas service provider" offering one-stop gas supply solutions. **Reporting lines (FY2025 annual report).** Main-business revenue is split into four lines: **Bulk gases:** (44.2% of FY2025 main-business revenue): oxygen, nitrogen, argon, carbon dioxide and acetylene, supplied as liquid in bulk tankers, in cylinders, and through gas stations. This is the largest line, and management calls it the company's "ballast stone". **Specialty gases:** (33.6%): ultra-pure ammonia, high-purity nitrous oxide, electronic-grade tetraethyl orthosilicate (TEOS), high-purity CO₂, high-purity hydrogen, helium, and newer fluorinated electronic gases (C₄F₆, C₄F₈, CH₃F). It also includes the electronic bulk carrier-gas service for fabs. **On-site gas generation and rental:** (13.5%): long-term air-separation and nitrogen-generation plants built on or beside customer sites, plus equipment rental. Contracts typically run 15–20 years. **Gas / clean fuel (燃气):** (8.7%): legacy natural-gas and clean-fuel distribution. **Revenue model.** Product sales dominate. Bulk and specialty gases are sold per unit (per kilogram, cubic metre or cylinder), under framework supply agreements for large accounts and spot pricing for small customers. On-site supply is a service-like, contracted model with long-dated take-or-pay structures. These typically combine a fixed facility charge with a variable gas charge, priced to recover the plant investment over the contract life. Cylinder rental is a small recurring rental stream. In 2026 the company also booked some electronic bulk carrier-gas installations as finance leases. This produced about CNY 40 million of asset-disposal gains in H1 2026, so revenue recognition in that business now mixes lease and service accounting. There is no meaningful licensing or subscription revenue. **Value-chain position.** Jinhong works in the midstream and downstream of the gas value chain. Upstream it buys crude ammonia, raw CO₂ streams, electricity (the dominant cost of air separation), liquid argon and nitrogen from third-party air-separation plants, and imported helium. It then: - purifies these into electronic grades; - produces liquid gases in its own air-separation units; - fills cylinders and tube trailers; - runs a logistics fleet of tankers, cylinder trucks and tube trailers; - operates on-site plants. Its competitive moat rests on four things: regional distribution density and safety licences; purification know-how for electronic-grade products; customer qualification, which is long and costly for semiconductor fabs; and the capital already sunk into on-site plants. **Customer types and end markets.** Customers range from thousands of small and medium manufacturers served by retail cylinders to large integrated-circuit makers. In semiconductors these include SMIC, an advanced-process logic fab in Beijing, SK Hynix's Wuxi and Dalian fabs, the Beijing North IC Technology Innovation Center, Guangdong Xinyueneng, CR Micro, Tianma and Laibao. Other large customers include optical-fibre groups (Hengtong, Sumitomo Electric), battery makers (CATL, supplied with high-purity helium since Q1 2026), photovoltaic and LED producers, and heavy industry for on-site supply (Yunnan Chenggang, Jishan Mingfu Steel, Jingjiang Special Steel, Yingkou Jianfa, Shandong Ruilin Polymer, Jiangsu Huaihe Chemical, CIMC Green Energy in Zhanjiang). In 2025 the company added more than 20 semiconductor customers, and in H1 2026 its integrated-circuit revenue grew 29.56% year on year. **Company's own description.** In its 2025 annual report, management describes 2025 in three parts: - Bulk retail: the company "wove a nationwide network" through new stations and regional M&A, entering Southeast Asia through the acquisition of Singapore's CHEM-GAS. - Specialty gases: it focused on "national strategic tracks" (semiconductors and new energy), building on import substitution of existing products while trial-producing several new products and breaking into overseas markets. - Helium: it is building a "globalised, self-controlled" supply system. On-site gas is presented as the "operational stabiliser". **Independent characterisation.** Jinhong is best understood as a regional Chinese packaged-and-liquid gas distributor that has grafted on two higher-value businesses: electronic specialty gases and long-term on-site supply. Its electronic-gas franchise is concentrated. Ultra-pure ammonia, the flagship, is largely sold into LED, display and photovoltaic nitride deposition, where oversupply and price competition in 2024–2025 compressed specialty-gas margins sharply. The average specialty-gas price fell from CNY 5.71/kg in 2023 to CNY 3.68/kg in 2024, and segment gross margin dropped from 40.36% to 27.69%. The strategic pivot to semiconductor-grade fluorinated etchants, fab carrier gases, helium and on-site ASUs is real and well funded. However, it has front-loaded capex (CNY 0.98–1.07 billion a year in 2023–2025) and depreciation ahead of revenue, so returns on capital have fallen to cyclical lows. The 2026 helium shock gave the company an unexpected tailwind that the market priced aggressively.

TWI is one of the few independent, founder-owned CMP pad makers left in the United States. It is a small Silicon Valley specialist that has outlasted a market now dominated by a few chemical and materials conglomerates. The company started with textile wipers and hard-disk-drive (HDD) polishing and texturing tapes. In the mid-1990s it used its knowledge of non-woven fibres and polyurethane to enter CMP. It became known in tungsten CMP: after a 1995 SEMATECH benchmark, TWI described itself as the world's largest supplier of tungsten CMP pads. Its technology combines the porosity of non-woven polyester with the hardness of solid polyurethane. It makes pads in sheets rather than cast cakes, and it holds patents on centrifugal casting of multilayer and optically transmissive pads. Its position today is niche. It serves tungsten, 200 mm and mature-node CMP, plus HDD tapes, through distributors in Europe and Asia. Its main appeal is lower cost of ownership: less slurry use, longer pad life and consistent pad-to-pad performance. --- **What the company does.** TWI designs, manufactures and sells consumable polishing materials used in two precision-manufacturing industries: 1. **Semiconductor fabrication.** It makes polishing pads for chemical mechanical planarization (CMP), the step that removes excess topography from silicon wafers after each metal or dielectric layer is deposited. TWI's pads are mainly used in tungsten CMP and also in oxide and copper/low-k steps. They have been qualified on all major polishing tool platforms, including Applied Materials' Mirra. 2. **Hard disk drive (HDD) manufacturing.** It makes textile polishing, texturing and wipe tapes used to finish disk media. Customers have included IBM, Komag, Akashic Memories and Showa Denko. **Company self-description.** TWI's website describes the company as an innovation leader in the HDD and semiconductor industries for more than 35 years. It says it offers customizable, durable product lines focused on CMP, backed by an in-house research and innovation team and a rigorous, personalized quality assurance system. Its standard description reads: "Located in Silicon Valley, Thomas West (TWI), incorporated in 1981, is a supplier of polishing, texturing and wipe tapes for hard disk drives (HDD), and polishing pads for Chemical Mechanical Planarization (CMP) in semiconductor manufacturing." **Business model.** TWI makes physical consumables and sells them as products. It does not disclose any subscription, licensing or service revenue. Its pads and tapes wear out in use, so demand follows customers' wafer starts and disk production rather than their capital-equipment cycles. That gives the business recurring revenue once a product is qualified. The CMP pad business follows the usual specialty-consumables pattern: a qualification at a fab takes a long time to win but tends to stay in place for years, because the fab must requalify its process before switching pads. TWI sells to customers in the United States directly and to customers in Europe and Asia through a network of semiconductor-supply distributors. **Revenue model mix.** **Product sales: CMP pads:** Role in the model: Main revenue line. Consumable pads sold per unit or per sheet. **Product sales: HDD tapes:** Role in the model: Long-standing second line. Polishing, texturing and wipe tapes for disk makers. **Product sales: backing films and accessories:** Role in the model: WestFilm carrier backing films for CMP polishing heads **Services:** Role in the model: Applications support from the Sunnyvale applications cleanroom. Not sold separately. **Licensing:** Role in the model: No out-licensing of the patent portfolio has been disclosed **Value-chain position.** TWI sits in the tier-two consumables layer of the semiconductor supply chain. Upstream are polyurethane prepolymers, curatives, non-woven polyester and adhesives. Downstream are wafer fabs and, through tool qualification, CMP equipment makers. Fabs buy its pads as process-of-record consumables. Pads are used with slurries from other suppliers, such as Entegris (CMC Materials), Fujimi, Resonac and Merck, so TWI's pitch rests on cutting slurry use, which its founder has said accounts for about 75% of total CMP consumable cost. **Customer types.** Integrated device manufacturers (IDMs) such as Texas Instruments; foundries and logic/analog fabs in Taiwan, China, Korea, Malaysia, the United States and Europe; mature-node 200 mm fabs; and HDD media makers. **End markets.** Semiconductor front-end fabrication (tungsten plug and interconnect CMP, oxide CMP, copper/low-k CMP), mostly at mature and specialty nodes; HDD media finishing; and other polishing uses named in the company's patents (metallurgical samples, optical components, lenses and photomask substrates). **Independent characterisation.** TWI is a niche, engineering-led consumables maker. At its peak in the early 2000s it was a real technology challenger in tungsten CMP. Since then its share has shrunk as DuPont (Rohm and Haas / Rodel), Entegris (CMC Materials / NexPlanar), Fujibo and, more recently, Chinese and Korean suppliers expanded. Its patent filings and distributor network are still active. However, it has made almost no public statements since about 2017. This suggests a company in maintenance mode, serving installed qualifications rather than competing for leading-edge process-of-record positions.

FNS Tech is a small-cap Korean supplier of process equipment and consumables that is moving from cyclical capital equipment to recurring semiconductor consumables. Its history is in wet-process equipment (cleaners, strippers, etchers, developers) for OLED display production, sold mainly to Samsung Display. Over the past decade it has built a materials and parts business. That business includes chemical-mechanical polishing (CMP) pads, a technology it acquired from InnoPad of the US in 2013 and localised in 2015. It also includes UV lamps and total-organic-carbon (TOC) units for ultrapure-water systems, and OLED mask and parts cleaning. In 2025 the company bought control of ASAHI LAMP, a Taiwanese maker of tungsten-halogen lamps for RTP and epitaxy tools that supplies Applied Materials and TSMC. In the first half of 2026, materials and parts made up 72% of revenue. CMP pads now ship for HBM3E/HBM4 production, and the company says it was the first to develop large-area CMP pads for glass-core packaging substrates. The investment case rests on high-margin consumables replacing lumpy display equipment as the main source of earnings. --- **Company description (FY2025 annual business report).** The company says it manufactures and sells equipment, parts and materials for semiconductor and display processes. It was founded to make flat-panel-display equipment and parts and materials for semiconductor manufacturing. For internal management it runs two operating units, Equipment Manufacturing and Parts & Materials. It reports a single segment because the two share customers, production sites and sales channels. **What the company does.** FNS Tech works in three areas of the fab supply chain: 1. **Display wet-process equipment.** It designs and builds turnkey wet stations for OLED and TFT-LCD panel lines: cleaners, strippers, etchers, developers and metal-mask cleaners, covering Gen-6 to Gen-8.6 IT panel lines. It has supplied OLED mass-production lines since 2009. It also offers roll-to-roll wet-process equipment and is extending its wet line-up to glass-core substrate processing (etching, cleaning, plating, developing, stripping, TGV processing). 2. **Semiconductor consumables and parts.** The products are polyurethane CMP pads (backside, recycled/reusable, and advanced-node/HBM grades, plus a new large-area glass-substrate pad), high-output UV lamps and TOC units for ultrapure-water treatment, and, through ASAHI LAMP, halogen lamps used as heat sources in rapid thermal processing (RTP) and epitaxial (EPI) deposition tools. 3. **Cleaning services.** These cover OLED fine-metal-mask and open-mask cleaning and process-part cleaning for display makers. **Business and revenue model.** Revenue is product revenue: equipment sold under project contracts and recognised as tools are delivered and accepted, and consumables sold on repeat purchase orders. Cleaning is a fee-for-service activity tied to customers' line utilisation. The company has no subscription or licensing revenue. The mix has changed sharply. Equipment was 72% of revenue in FY2024 and 53% in FY2025. Materials and parts reached 72% in the first half of 2026. SK Securities estimates that materials and parts generate about 90% of operating profit. At ASAHI LAMP, about 85% of revenue comes from aftermarket replacement sales rather than OEM tool shipments. **Value-chain position.** In display, FNS Tech is a tier-1 equipment vendor to panel makers. In semiconductors it is a tier-1 consumables supplier to device makers (Samsung Electronics, SK hynix, Micron, TSMC, CXMT). Through ASAHI LAMP it is also a component supplier to equipment OEMs (Applied Materials) and to fabs buying aftermarket lamps. **Customer types and end-markets.** Named customers include Samsung Display, Samsung Electronics, SK hynix, TSMC, CXMT and Chemtronics. ASAHI LAMP's customers include Applied Materials, TSMC, Micron, Samsung Electronics, SK hynix, and Chinese and Taiwanese foundries and toolmakers. End-markets are OLED panels for IT devices and foldables, DRAM and HBM memory, NAND, leading-edge and mature foundry, and advanced packaging (glass-core substrates for AI accelerators). **Independent characterisation.** FNS Tech is best seen as a consumables company growing inside a shrinking display-equipment shell. Display equipment depends on Samsung Display's capital spending, which has been irregular. In 2024 the company described its main display customer as bringing some OLED front-end wet equipment in-house. The consumables business, by contrast, has recurring demand linked to wafer starts, HBM stack counts and the number of CMP steps per wafer. It also has structurally higher margins: lamps and pads run at operating margins above 30%, and ASAHI LAMP at about 50%. The open question is whether CMP pads can grow beyond a niche position against Qnity (formerly DuPont), which holds roughly 80% of the global market.

IV Technologies was the first Taiwanese company to break the near-monopoly of the US majors in CMP polishing pads using its own technology. It is now the only domestic CMP pad supplier qualified at Taiwan's leading foundries, memory makers and packaging houses. The company grew out of a polyurethane (PU) chemicals business founded in 1986 and controls its whole value chain, from in-house PU synthesis and pore-forming chemistry through groove design and machining. It says it is the only company that makes CMP pads by reaction injection molding (RIM). It holds 142 patents in Taiwan, the US and China and has shipped more than 1.1 million pads. Its global CMP pad share is about 3 to 4%, against roughly 80% for the DuPont business now operating as Qnity Electronics. Management aims to reach 10% through advanced-packaging pads for CoWoS and SoIC, a new soft-pad line for CoWoS-L, silicone membranes, and dual production bases in Taiwan and mainland China that serve customers in both markets as supply chains are localized. Customers include TSMC, Micron and Nexchip. The financial profile is that of a high-margin specialty-materials company: consolidated gross margin was 53.9% in the first half of 2026, and the semiconductor line earns above the group average. --- **What the company does.** IV Technologies designs, formulates, manufactures and services polymer polishing pads for the CMP step in semiconductor manufacturing. CMP flattens the wafer surface between lithography, deposition and etch layers. It is repeated many times per wafer, and the number of steps rises as logic nodes shrink, as 3D NAND gains layers and as advanced packaging adds hybrid-bonding and redistribution layers. The pad works alongside the slurry, the diamond disc conditioner and the wafer. Its hardness, compressibility, pore structure and groove pattern determine removal rate, uniformity and defect levels. Management estimates that the pad accounts for about one third of the cost of CMP consumables. The group also makes polishing-head silicone membranes, soft polishing pads, sub-pads and pads with endpoint-detection windows. Its customers span reclaimed wafers and wafer substrates, logic and memory front-end fabs, and back-end advanced packaging. **The parent's own description.** PVI describes itself as a group built on PU materials technology with three product lines: "semiconductor polishing pads and consumables," "medical and sports products," and "green, environmentally friendly adhesives," with the semiconductor polishing pad business as its strategic focus. Its description of IV Technologies is the subsidiary that first broke the international majors' monopoly in CMP polishing pads with proprietary technology, with products adopted across the upstream, midstream and downstream semiconductor supply chain. The group's chemicals and medical businesses sit mainly in a second subsidiary, PVI Chemical Co. (久陞昌企業). That subsidiary is the exclusive contract manufacturer of medical insoles for Dr. Scholl's, North America's largest insole brand, and holds about 18% of the North American professional medical insole market. **Business and revenue model.** **Product sales, no licensing or subscriptions:** Pads are high-value consumables used up on every wafer. Revenue therefore tracks wafer starts and the number of CMP steps per wafer rather than tool purchases, which makes this a replacement business and not a capital-equipment one. **Specification-driven qualification:** Each pad is qualified for a specific customer, tool, slurry, disc and process step. Management says a new pad must deliver at least 30% better value to the customer before it is adopted. As of June 2026 the company had 212 products in mass production and 403 development projects. Once qualified, a pad is rarely displaced, so revenue is sticky. **Consignment and vendor-managed inventory:** In mid-2026 the largest customer switched from invoice-on-shipment to consignment, with revenue recognized when the pad is used. That pushed recognition back by about six weeks in June and July 2026. **Value-chain position:** IV Technologies sits in Tier-1 materials: it supplies fabs directly and works with tool makers. It synthesizes key PU prepolymers within the group and keeps about six months of raw-material inventory. That gives it more control over costs and supply than competitors that buy PU systems from outside. **Customer types and end-markets.** **Wafer substrate / reclaim:** Examples (disclosed in public reporting): GlobalWafers (supply-chain reports); reclaim-wafer houses; Pad applications: Stock removal and final polishing of silicon substrates and reclaimed wafers **Foundry: advanced and mature logic:** Examples (disclosed in public reporting): TSMC, UMC, Powerchip (PSMC), Nexchip; Pad applications: Oxide, STI, tungsten and copper CMP steps; advanced-node FEOL and BEOL **Memory:** Examples (disclosed in public reporting): Micron, Macronix, Winbond; Powerchip's DRAM legacy (first adopter, 2003); Pad applications: DRAM and NAND dielectric and metal CMP **Advanced packaging / OSAT:** Examples (disclosed in public reporting): ASE; foundry-run CoWoS and SoIC lines; Pad applications: Redistribution-layer, interposer and hybrid-bonding planarization; CoWoS-L soft-pad steps **Independent characterization.** IV Technologies is a niche challenger with real qualification depth in a market controlled by one US supplier. Its competitive edge does not come from scale. It comes from three things. First, a cost and design advantage from RIM and single-piece free-foaming. Second, chemistry it controls, including water-blown carbon dioxide pores that avoid some solvent-based blowing agents. Third, its position as the domestic second source to the world's most important foundry, at a time when fabs want supply diversity and the US-China split is pushing Chinese fabs away from US vendors. Revenue is split almost equally between Taiwan and mainland China, so IV Technologies benefits from localization pressure on both sides of the Strait. The consolidated group still carries a lower-margin non-semiconductor business, about one third of revenue, which dilutes reported growth and margins but provides cash flow.

Enpulse is Korea's leading domestic producer of CMP polishing pads, the polyurethane consumable used with slurry to planarize wafers after deposition, etch and lithography. It started in 2015 as an import-substitution project inside SKC and broke into a market where two U.S. suppliers have historically held more than 90% of global share. It qualified pads at Korean memory and foundry fabs and, by its own account, overtook DuPont as the leading pad supplier at a major Korean customer in March 2021. Its differentiators are in-house prepolymer and additive synthesis, a hybrid pore system that combines solid microspheres with inert-gas foaming, single-sheet casting, and a highly automated Cheonan plant. Since the 2025 carve-out under Hahn & Company, Enpulse has been a standalone pure-play pad company. It is widening qualifications to Chinese and Taiwanese chipmakers, building a Yongin R&D center, and marketing VDC-free, MOCA-free, chlorine-reduced and bio-based pads. Its scale is small next to the market leaders. Last disclosed annual revenue was KRW 40.3 billion (FY2023). **Relationship to "SK enpulse":** Global CMP pad market studies, including the Global CMP Pads Market reports, list this business as "SK enpulse." Until April 2025 the CMP pad operation was a division of SK enpulse Co., Ltd. (formerly SKC Solmics, KOSDAQ: 057500), a wholly owned semiconductor-materials subsidiary of SKC Co., Ltd. (KRX: 011790). Private equity firm Hahn & Company agreed to buy the division in December 2024 through a special-purpose company, Hahn & Co No. 32 Co., Ltd. The deal closed on 4 April 2025 at KRW 334.6 billion, and the acquiring company took the name Enpulse Co., Ltd. that month. The former parent, SK enpulse, sold or spun off its other businesses and was merged into SKC on 22 December 2025. It no longer exists as a separate company. Enpulse Co., Ltd. is the only current entity that makes and sells the CMP pads tracked under the "SK enpulse" name. **What the company does.** Enpulse designs, makes and sells CMP polishing pads for semiconductor wafer fabrication and does related R&D. The company lists its business scope as "CMP Pad manufacturing and sales, and research and development." It has no other product line. Before the carve-out, SK enpulse also ran blank masks, CMP slurry, testers and EFEM equipment. None of those businesses moved to Enpulse. The blank mask and slurry units were sold to other buyers, and the back-end equipment business went to ISC Co., Ltd. **Company self-description.** The corporate website calls Enpulse a CMP Pad technology company that aims to become "Global No.1" in semiconductor CMP pads. It says it offers a "total solution" that integrates development, production, quality and safety, health and environment (SHE). It highlights a fully automated smart factory with real-time data, customer-specific pad design backed by integrated evaluation and analysis, and SHE-based management. The CEO message says Enpulse began developing CMP pads in 2015 in Korea, which then had no domestic CMP pad industry. It also says the company built the world's first fully automated CMP pad smart factory in Cheonan in 2020 and is building a Yongin research center for basic and product-development R&D. "Global No.1" is a stated ambition. On available market data, Enpulse is a mid-tier supplier by global revenue. **Business model and revenue model.** Revenue comes entirely from product sales of a recurring, high-turnover fab consumable. Pads wear out and are replaced at regular intervals on each CMP platen, so demand tracks wafer starts and the number of CMP steps per wafer. The number of CMP steps rises with 3D NAND layer counts, DRAM and HBM complexity, and advanced logic interconnect layers. No service, subscription or licensing revenue has been disclosed. Pads are qualified process-of-record (POR) materials. Each design-in follows months to years of joint development and fab qualification for a specific layer, slurry and tool. Once a pad is qualified, switching costs are high and volumes are sticky. That makes qualification wins the main leading indicator of future revenue. **Value-chain position.** Enpulse sits in the front-end fab-materials layer. Upstream, it buys isocyanates, polyols, curing agents, microspheres and sub-pad laminates. Its stated advantage is that it synthesizes its own prepolymers and additives rather than buying finished prepolymer. Downstream, it sells directly to integrated device manufacturers (memory and logic) and foundries running 200 mm and 300 mm lines. CMP tool makers and slurry suppliers are partners in co-optimization. **Customer types and end-markets.** The customers are memory IDMs, logic and foundry fabs, and 200 mm specialty foundries. Korean press reports name SK hynix and DB HiTek as main supply relationships. Enpulse's corporate history gives anonymized qualification records with customers in Korea ("S", "D", "O"), China ("I", "S") and Taiwan ("M"). The English site claims more than 100 global clients but names none. The end-markets are DRAM and HBM, 3D NAND, foundry and logic, and mature-node analog and power devices on 200 mm. **Independent characterization.** Enpulse is a focused, sub-scale challenger in a concentrated oligopoly. Qnity (formerly DuPont Electronics) and Entegris (which absorbed CMC Materials) lead the market. Hubei Dinglong is scaling fast inside China. Enpulse's advantages are proximity to Korean memory fabs, vertical integration into raw materials and a demonstrated record of qualifications. Its weaknesses are revenue concentration, scale (about 180,000 pads a year of installed capacity against Dinglong's roughly 600,000 target), and the change in ownership, which turned a captive SK-group supplier into an independent PE-owned company. The investment case rests on diversifying customers in China and Taiwan, moving the mix to advanced nodes, and margin recovery that began in 2024.
