Introduction
The global semiconductor photomask blanks market is highly consolidated. A small number of Japanese companies supply the great majority of blanks by value, and concentration is greatest in the most advanced product types: EUV blanks are produced in volume by only two suppliers, HOYA and AGC, while high-end ArF phase-shift and opaque molybdenum-silicide blanks are supplied mainly by HOYA and Shin-Etsu Chemical. Competition is broader in mature-node chrome and binary blanks, where S&S Tech, ULVAC Coating Corporation, AGC and smaller suppliers, including Telic Company in the United States and a growing number of Chinese producers, compete for the business of merchant mask makers, specialty fabs and research users. Upstream, low-thermal-expansion glass for EUV substrates is supplied by AGC and Corning, which gives these companies an additional role in the competitive structure of the EUV segment.
The nature of competition is shaped by technology, qualification and long-term relationships rather than by price. Blank suppliers compete on defect density, flatness, film uniformity and stability, the completeness of the metrology data supplied with each blank, delivery reliability and their ability to co-develop new blank types with leading customers. Qualification at a major mask shop takes one to three years and must be repeated at each node, so incumbents with established qualifications enjoy durable advantages, and market shares change mainly at node transitions. Price competition is more evident in mature-node products, especially in China, where domestic suppliers are entering with policy support.
The competitive environment has become more dynamic since 2024. Capacity expansions by HOYA and AGC, the progress of S&S Tech toward EUV blank qualification in South Korea, and the entry of Changzhou Fusion New Material through its acquisition of SK enpulse's blank business in 2025 indicate that the market is attracting investment from both incumbents and new entrants. Export controls and supply-chain localisation policies are encouraging the emergence of regional suppliers, while the arrival of High-NA EUV and new EUV absorber architectures is opening a new phase of technology competition among the leaders.
Key Player Positioning
The leaders of the market are HOYA Corporation, AGC Inc. and Shin-Etsu Chemical. HOYA is the largest supplier of photomask blanks overall and the leading supplier of EUV blanks, with production in Japan and Singapore, a broad portfolio covering EUV and optical blanks, and a position as a qualified supplier for the most advanced layers of leading logic customers; its decision in April 2026 to build a new EUV blank building in Singapore reinforces its capacity leadership. AGC is the second volume supplier of EUV blanks and the only producer that covers every step from low-thermal-expansion glass to finished EUV blank, with production at AGC Electronics in Fukushima Prefecture expanded in several phases since 2020 and blanks adopted by multiple logic and memory manufacturers. Shin-Etsu Chemical is a leading supplier of advanced optical blanks, including ArF attenuated phase-shift and opaque molybdenum-silicide binary blanks, with in-house synthetic quartz substrates and photoresist capabilities, production at its Naoetsu and Takefu plants, and a new lithography materials base in Gunma. These three companies are classified as leaders because of their scale, technology leadership, breadth of qualification at leading mask shops and long industry experience.
The challengers are S&S Tech, ULVAC Coating Corporation and Changzhou Fusion New Material through its Lumina Mask business. S&S Tech, founded in 2001 and based in Daegu, South Korea, is an established supplier of optical blanks for semiconductor and display applications, with strong positions at South Korean memory and foundry customers, and it is working to become the first EUV blank supplier outside Japan, having completed an EUV-dedicated centre in Yongin in October 2025 and placed EUV blanks in customer testing. ULVAC Coating Corporation, a subsidiary of ULVAC with its main plant in Chichibu, Japan, and affiliates in Taiwan and China, is a long-standing supplier of hard mask blanks for general-use semiconductors and large blanks for display production. Changzhou Fusion New Material entered the market by acquiring SK enpulse's blank business, which supplies ArF and KrF phase-shift blanks, and plans to expand capacity in South Korea and build a plant in Shanghai to serve Chinese mask shops. These companies are classified as challengers because they have established products and customers but lack the breadth of advanced qualifications held by the leaders, or are in the process of building them.
The niche players are Corning Incorporated and Telic Company. Corning supplies ultra-low-expansion glass used as a substrate for EUV blanks, giving it a specialised but strategically important role in the EUV supply chain, without competing in finished blanks. Telic Company, founded in 1968 and based in Valencia, California, produces chrome photomask blanks and coated substrates for semiconductor research, MEMS, microfluidics, optics and holography, serving mainly North American research and specialty customers with flexible, small-lot products. Both companies hold positions defined by specific capabilities rather than by broad market coverage.
The competitive structure of the photomask blanks market can be analysed through the five forces that determine industry profitability: the threat of new entrants, the bargaining power of suppliers, the bargaining power of buyers, the threat of substitutes, and the intensity of competitive rivalry. This analysis considers each force in the context of the market's technology, its concentrated supply and demand, and the policy environment of 2025 and 2026, and assigns a rating of high, medium or low to each.
The threat of new entrants is rated low. Entry into the photomask blanks market, particularly at the advanced end, requires mastery of several demanding technologies at once: substrate preparation or reliable access to top-grade substrates, defect-free thin-film deposition, film engineering for optical properties and etch behaviour, high-sensitivity inspection, and clean handling and packaging. Each of these requires substantial capital investment in specialised tools with long delivery times, and the combined investment must be made years before any revenue is earned. Even when a new entrant can produce technically acceptable blanks, it must pass qualification processes at mask shops and fabs that typically last one to three years and that are repeated for each node and layer group. Incumbents benefit from decades of process learning, extensive patent portfolios on film stacks and processes, and long relationships with the leading buyers, who are reluctant to take risks with the starting material of their most critical masks. The capital required is not only financial but also organisational: a new entrant must build quality systems, contamination-control disciplines and customer-support capabilities that meet the expectations of the world's most demanding manufacturing customers.
Entry is not impossible, and policy support has lowered barriers in some segments. South Korea's support for domestic materials suppliers has helped S&S Tech progress toward EUV blank supply, and Chinese policy favouring domestic semiconductor materials has encouraged new entrants into optical blanks, including Changzhou Fusion New Material through its acquisition of SK enpulse's blank business in 2025. These entrants, however, illustrate how difficult entry is: S&S Tech has been developing EUV blanks since 2020 and was still in customer testing in 2026, and the Chinese entrant chose to buy an established business with existing qualifications rather than develop one from scratch. Entry is easier in mature-node chrome blanks, where specifications are less demanding and customers are more numerous, but even there, margins are modest and incumbents with established capacity can compete effectively on price and service. Overall, the threat of new entrants remains low across the forecast period, with some increase in mature optical categories in China. Potential entrants from adjacent industries, such as display blank makers, optical coating companies or semiconductor materials groups, face the same hurdles.
Display blanks use larger substrates and less stringent defect specifications, and while display blank makers possess sputtering and handling expertise, their processes are not directly transferable to semiconductor blanks. Equipment makers that supply deposition tools to blank makers, including companies that have considered entering EUV blank production in the past, have generally chosen to remain suppliers rather than competitors, partly because entry would conflict with their customer relationships. The time and capital required to reach qualification at leading customers therefore act as a durable barrier that the forecast does not expect to erode significantly before 2032.
The bargaining power of suppliers is rated medium. Blank makers depend on a small number of suppliers for several critical inputs and tools. Low-thermal-expansion glass for EUV substrates is produced by very few companies, ion beam deposition systems for EUV multilayers come predominantly from Veeco, blank inspection relies heavily on Lasertec, and high-purity sputtering targets and synthetic quartz are supplied by specialised producers. These suppliers have meaningful power, especially when demand rises quickly and their delivery times lengthen. However, several factors limit their leverage. The leading blank makers are large companies with significant purchasing power and long-term relationships with their suppliers; some are vertically integrated, as AGC is in low-thermal-expansion glass and Shin-Etsu Chemical is in synthetic quartz and resists. Equipment suppliers also depend on blank makers as a key customer segment for specialised tools, which encourages cooperative development rather than aggressive pricing. The balance between these considerations supports a medium rating, with supplier power highest for EUV-specific inputs and lowest for mature-node materials. Supplier power has been visible in recent years in the form of extended lead times rather than sharp price increases.
When EUV blank makers announced capacity expansions in 2022 and 2023, the delivery of ion beam deposition and inspection tools set the pace at which new capacity could come on line, and the industry's reliance on a single dominant supplier of EUV blank deposition systems was widely discussed. Blank makers have mitigated this exposure by placing orders early, by working with tool vendors on joint development roadmaps, and in some cases by developing in-house tool modifications. Over the forecast period, supplier power is expected to remain medium, with the introduction of High-NA blanks temporarily increasing the leverage of suppliers whose tools are needed for new absorber deposition and actinic inspection.
The bargaining power of buyers is also rated medium. On one side, the buyer base is highly concentrated: a handful of captive mask shops at the largest foundries, logic IDMs and memory makers account for most of the value of advanced blanks, and these buyers negotiate long-term agreements, demand detailed specifications and engage closely in product development. Their scale gives them considerable leverage on pricing and allocation, and their ability to support a second source, as Samsung has done with S&S Tech, provides a credible alternative over time. On the other side, the number of qualified suppliers for each advanced blank type is very small, switching costs are high because of qualification requirements, and the cost of blanks is small relative to the value of the wafers patterned with the finished masks. Buyers therefore prioritise quality and security of supply over price, which limits the degree to which they can exert price pressure. Merchant mask shops, which buy in smaller volumes and have less influence on product development, have weaker bargaining power than captive buyers, especially for advanced products, but they have more alternatives in mature-node categories where several suppliers compete. Buyer power differs by region and by product type.
In China, where export controls limit access to some foreign products and where domestic suppliers are emerging, buyers of optical blanks have growing leverage because they can credibly threaten to shift volume to local suppliers. In South Korea, Samsung's support for a domestic EUV blank supplier strengthens its negotiating position with Japanese incumbents. In the United States and Europe, where buyers are fewer and import all of their blanks, buyer power is weaker, although it is reinforced by government interest in supply security. Over the forecast period, buyer power is expected to rise modestly as second sources qualify, but the scarcity of qualified supply for the most advanced products will keep it at a medium level.
The threat of substitutes is rated low. Photomask-based optical and EUV projection lithography remains the only technology capable of patterning semiconductor wafers at the volumes and costs required by the industry, and every lithography layer requires a mask made from a blank. Alternative patterning methods exist but have not displaced masks. Electron-beam direct write is used for research, prototyping and some low-volume specialty devices, but its throughput is far too low for volume production. Nanoimprint lithography has advanced, with Canon delivering a nanoimprint system to the Texas Institute for Electronics in 2024 for research and prototyping, and it is being evaluated for certain memory layers; however, nanoimprint templates are themselves produced from quartz blanks and master templates written by electron beam, so nanoimprint would shift rather than eliminate blank demand. Directed self-assembly and other complementary techniques are used to enhance lithography rather than replace it. Within the market, substitution between blank types occurs as layers move from ArF multi-patterning to EUV, but this represents a change in product mix rather than a threat to the market as a whole.
Mask reuse and longer mask lifetimes could, in principle, reduce blank demand, and improvements in pellicle technology, cleaning processes and mask durability have extended the useful life of masks, particularly for EUV. However, these improvements mainly reduce replacement demand for high-volume products and have little effect on the number of new mask sets created for new designs and revisions, which is the main driver of blank consumption. Similarly, multi-project wafers reduce the number of mask sets per design but increase the number of designs that reach silicon. The net effect of these practices is modest, and they do not alter the low rating of the threat of substitutes.
The intensity of competitive rivalry is rated medium. In EUV blanks, competition takes place between two established suppliers with very high barriers to entry and with customers that often dual-source, so rivalry centres on technology leadership, defect performance, capacity and qualification at new nodes rather than on aggressive price competition. In high-end optical blanks, a small number of suppliers compete for qualification at leading mask shops, and rivalry is shaped by film innovation and quality. In mature-node chrome and binary blanks, more suppliers compete and price competition is stronger, especially in China, where domestic entrants are seeking share with policy support. The overall growth of the market, driven by EUV layer counts and fab expansion, moderates rivalry by allowing suppliers to grow without taking share from one another, and the high fixed costs of the business encourage disciplined capacity additions. Rivalry is expected to intensify gradually as second sources qualify in EUV and as Chinese suppliers expand in optical blanks, but it is unlikely to reach high levels during the forecast period. The nature of rivalry is also influenced by the market's dependence on technology transitions.
At each new node, blank suppliers compete to be qualified first for the most critical layers, and the supplier that wins these qualifications typically gains a large share of the node's blank volume for several years. This creates periods of intense technical competition around node introductions, separated by periods of relative stability. The arrival of High-NA EUV and EUV phase-shift blanks will create one such period during the forecast, as suppliers compete for qualification on new absorber stacks. Price competition is more continuous in mature-node categories, where products are well established and customers can compare suppliers more easily.
Taken together, the five forces describe a market with structurally favourable conditions for established suppliers. Low threats of entry and substitution protect incumbents' positions, while medium supplier and buyer power and medium rivalry limit the extent to which any participant can capture an excessive share of value. The forces are, however, shifting gradually: policy-supported entry in South Korea and China, the growing importance of a few very large buyers, and the technology transition to High-NA all point to a market in which competitive pressure rises modestly over the forecast period, most noticeably in optical blank categories and among memory buyers. Table 5.1 presents the resulting ratings.
Threat of New Entrants: Low; High capital requirements, deep process know-how, patent portfolios and multi-year qualification at mask shops and fabs.
Bargaining Power of Suppliers: Medium; Concentrated supply of low-thermal-expansion glass, ion beam deposition and inspection tools, offset by the scale and partial vertical integration of blank makers.
Bargaining Power of Buyers: Medium; Highly concentrated captive buyers with strong leverage, balanced by few qualified suppliers, high switching costs and low blank cost relative to wafer value.
Threat of Substitutes: Low; No alternative to mask-based lithography for volume production; nanoimprint templates also start from quartz blanks.
Competitive Rivalry: Medium; Duopoly in EUV and few suppliers in high-end optical blanks, with stronger price competition in mature chrome blanks and among Chinese entrants.
