Introduction – Addressing Core Industry Pain Points
The global semiconductor, flat-panel display (FPD), and precision optics industries face a persistent challenge: producing photomasks with high-resolution pattern fidelity, low defect density, and dimensional stability for advanced lithography processes (EUV, DUV, i-line, g-line). Photomasks are master templates used to project circuit patterns onto wafers (semiconductors) or glass substrates (FPDs). The starting material—mask blanks—must have ultra-flat surfaces, uniform light-blocking films, and defect-free photoresist coatings. Foundries, IDMs, and display manufacturers increasingly demand chrome mask blanks with spin-coated photoresist—photomask blanks consisting of a transparent substrate (typically synthetic quartz for high transmission, low thermal expansion, or high-grade soda lime glass for cost-sensitive applications) coated with a uniform, dense chrome (Cr) light-blocking film (40-100nm thickness, 2-5% reflectivity), followed by a uniform photoresist layer (e-beam sensitive or laser sensitive) on top. The chrome film blocks exposure light (UV, DUV, EUV), while the photoresist enables precise pattern transfer during electron-beam or laser writing. This type of blank is a critical intermediate material for fabricating photomasks in semiconductor (logic, memory, foundry), flat-panel display (LCD, OLED, microLED), and precision optical device manufacturing (diffractive optics, gratings), offering high coating uniformity (thickness variation <1-2%), strong adhesion (chrome to glass, resist to chrome), and excellent dimensional stability (low thermal expansion).

Market Sizing & Growth Trajectory
The global market for Chrome Mask Blanks was estimated to be worth US$ 3,228 million in 2025 and is projected to reach US$ 4,921 million, growing at a CAGR of 6.3% from 2026 to 2032. In 2024, global Chrome Mask Blanks production reached approximately 234,700 square meters, with an average global market price of around US$ 13,750 per square meter (based on US$3,228M/0.235M m² ≈ $13,750). According to QYResearch’s interim tracking (January–June 2026), the market is driven by: (1) advanced semiconductor nodes (3nm, 2nm, 1.4nm) requiring high-end quartz mask blanks, (2) flat-panel display (FPD) capacity expansion (Gen 10.5+ for 65-85″ TVs), (3) EUV lithography adoption (13.5nm wavelength) requiring defect-free, ultra-low thermal expansion mask blanks. The quartz substrate segment dominates (65-70% market share, high transmission (DUV/EUV), low thermal expansion (CTE 0.5 ppm/°C)), with soda lime (SL) substrate (20-25%, cost-sensitive, i-line/g-line) and others (5-10%). Semiconductors account for 60-65% of demand, flat-panel displays 25-30%, hard disk drives (HDD) 5-8%, and others (optics, MEMS) 2-5%.

From a mask blank manufacturing perspective (substrate polishing, thin-film deposition, photoresist coating), chrome mask blanks differ from uncoated glass substrates through: (1) super-polished surface (Ra <0.2nm for quartz), (2) chrome sputter deposition (DC magnetron, Cr or CrO targets, thickness uniformity <1%), (3) photoresist spin coating (uniformity <2%, defect density <0.01-0.1/cm²), (4) hardmask layers (CrO, CrON for etch resistance), (5) anti-reflective coating (ARC) for reduced reflectivity.
Six-Month Trends (H1 2026)
Three trends reshape the market: (1) EUV mask blank development – Reflective mask blanks (Mo/Si multilayers + capping layer + absorber) for EUV (13.5nm), requiring defect-free substrates (<0.001 defects/cm²), ultra-low thermal expansion (ULE, Zerodur), and specialized deposition (ion beam deposition); (2) Large-area mask blanks for FPDs – Gen 10.5+ substrates (2940mm x 3370mm) for 65-85″ TV panels, requiring square meter-scale chrome mask blanks (multiple-up patterning); (3) Photoresist innovation – High-sensitivity e-beam resists (ZEP, HSQ) for faster writing time (2-5x throughput), reducing mask manufacturing cost.
User Case Example – EUV Mask Blank Development, Japan
A Japanese mask blank supplier (Shin-Etsu) developed EUV mask blanks (reflective, Mo/Si multilayer, Ru capping layer, TaBN absorber) for 3nm logic node (TSMC, Samsung). Specifications: substrate flatness <50nm (over 6″ x 6″), defect density <0.001/cm² (zero printable defects), multilayer reflectivity >68% at 13.5nm. Results (2025): mask blank cost $10,000-15,000 per unit (vs. $3,000-5,000 for DUV mask blanks). Supplier shipped 1,000+ units for 3nm pilot line.
Technical Challenge – Defect Density and Substrate Flatness
A key technical challenge for chrome mask blank manufacturers is achieving extremely low defect density (<0.01-0.001/cm² for advanced nodes) and sub-micron flatness for high-NA lithography (EUV, DUV immersion):

| Defect density (chrome film) | <0.01/cm² | Pinholes, nodules, particles during sputtering | High-purity targets (Cr 99.99%), DC magnetron sputtering (low particle generation), in-situ inspection (darkfield), repair (focused ion beam (FIB)) |
| Defect density (photoresist) | <0.01/cm² | Particles, bubbles, striations (non-uniform coating) | Point-of-use filtration (0.02-0.1μm), spin coating (dynamic dispense, edge bead removal), Class 1 environment |
| Substrate flatness (6″ x 6″) | <0.5μm (peak-to-valley) | Warpage from polishing, mounting, film stress | Double-side polishing (DSP), stress-balanced chrome films (Cr + CrO), stress relief anneal |
