Advanced Semiconductor Packaging Opens another Manufacturing Frontier for the Optical Quartz Market

Optical quartz is becoming increasingly important in semiconductor manufacturing, where even microscopic material imperfections can influence optical performance, wafer processing accuracy and equipment reliability. The Optical Quartz Market covers high-purity fused silica, synthetic silica glass, optical-grade quartz and precision-engineered quartz components used in lithography systems, photomask production, inspection equipment and advanced semiconductor processing.

• Its importance extends beyond transparency. Manufacturers require tightly controlled refractive index, low thermal expansion, high ultraviolet transmission and minimal contamination.
• These properties make optical quartz particularly relevant as semiconductor manufacturers introduce increasingly sophisticated patterning technologies and more demanding wafer-processing requirements.

Why Lithography Is Rewriting Optical Material Specifications?

The transition towards advanced lithography is changing the requirements for optical materials. Deep ultraviolet (DUV) lithography uses 248 nm KrF and 193 nm ArF excimer laser wavelengths, requiring materials with excellent ultraviolet transmission and resistance to laser-induced degradation.

Corning’s HPFS fused silica is specifically developed for semiconductor lithography optics, including i-line, KrF and ArF applications. Its high-purity material grades support optical components such as lenses, prisms, flats and mirrors.

An important distinction is that EUV lithography operates at 13.5 nm and relies on multilayer reflective optics rather than conventional transmissive quartz lenses. Nevertheless, ultra-low expansion glass remains important for EUV photomask substrates. Corning’s ULE glass is specifically designed for this application. This creates two related but technically distinct material opportunities within advanced lithography.

The 300 mm Wafer Era Is Increasing Precision Requirements

• The semiconductor industry’s movement towards 300 mm wafer manufacturing has increased the importance of dimensional consistency in optical and precision glass components.
• Corning’s HPFS fused silica wafer specifications include diameters of 100 mm, 150 mm, 200 mm and 300 mm, with thickness options ranging from 0.30 mm to 20 mm. These specifications illustrate the material’s versatility in optical substrates, micro-optics and semiconductor-related applications.
• Meanwhile, SCHOTT supplies high-purity quartz base materials in near-net-shape geometries for semiconductor equipment manufacturers. Its Ilmasil quartz components support wafer processing, plasma etching and other front-end manufacturing operations.
• These developments show how optical quartz suppliers are increasingly expected to deliver application-specific material geometries rather than only conventional glass blanks.

High-NA EUV Is Changing the Requirements for Optical Engineering

The introduction of High Numerical Aperture EUV lithography represents an important development in advanced chip manufacturing. ASML’s EXE platform uses a numerical aperture of 0.55 compared with 0.33 for conventional Low-NA EUV systems.

This transition increases the importance of optical precision, mask qualification and thermal stability. ZEISS announced the global deployment of its AIMS EUV 3.0 mask qualification systems in February 2026, including capabilities for both Low-NA and High-NA EUV scanner matching.

Although these systems do not directly translate into equivalent demand for transmissive quartz optics, they demonstrate how increasingly sophisticated lithography equipment is raising material and metrology requirements throughout the semiconductor optical supply chain.

Where Quartz Components Meet Plasma Etching and Wafer Processing

Optical quartz also has an important role beyond imaging and lithography. Semiconductor fabrication involves high-temperature processing, plasma exposure and chemically demanding environments, creating requirements for specialized quartz components.

• SCHOTT identifies operating temperatures of approximately 1,100–1,300°C for its Ilmasil quartz glass semiconductor applications. These materials are used in etch rings, liners, flanges and other precision components.

Tosoh Quartz also manufactures transparent, opaque and black quartz glass components, offering machining processes such as grooving, circular-hole fabrication and optical polishing. Its precision products support semiconductor manufacturing and optical inspection equipment.

The New Material Competition Is About Purity and Optical Stability

• A significant development in the Optical Quartz Market is the increasing differentiation between synthetic fused silica, natural fused quartz and specialty optical glass.
• Synthetic fused silica offers tightly controlled optical homogeneity and low impurity levels, making it particularly valuable for deep-ultraviolet lithography.
• Nikon’s NIFS synthetic silica series supports ultraviolet optics, semiconductor photomask substrates and lithography equipment.
• HOYA also maintains an important position in semiconductor mask blanks, supplying substrates for both DUV and EUV photomask production. Its 2025 integrated report identifies mask blanks as a major product category within its information technology business.
• These developments highlight how optical quartz and related specialty glass materials are becoming integral to semiconductor pattern transfer, inspection and advanced optical engineering.

The Next Opportunity Lies in Combining Optical and Thermal Performance

The Optical Quartz Market is moving towards increasingly specialized material requirements, particularly as semiconductor manufacturers demand higher optical transmission, dimensional stability and contamination control. AI-related chip manufacturing, advanced lithography, photomask qualification and precision wafer processing are creating interconnected applications for high-purity quartz and specialty glass.

The next stage of industry development will depend on material homogeneity, advanced finishing, coating technologies and application-specific component engineering. Suppliers capable of combining optical performance with consistent manufacturing quality will remain important to the development of increasingly complex semiconductor production systems.
