‌Applications of Synthetic Quartz Products in Semiconductor and Optical Fields

Ⅰ. Semiconductor Field‌
‌1. Critical Components in Integrated Circuit (IC) Manufacturing‌

• ‌High-temperature processes‌ (e.g., diffusion, oxidation):

• Synthetic quartz components with high-temperature resistance (>1000°C), low hydroxyl (OH) content (e.g., furnace tubes, boat holders, bell jars) require dehydroxylation treatment to enhance thermal stability .

• Quartz flanges are paired with diffusion tubes for diffusion, oxidation, and CVD processes in monocrystalline silicon wafer production .

• ‌Low-temperature processes‌ (e.g., etching, lithography, cleaning):

• Quartz components with corrosion resistance, high transparency, and ultra-low impurities (e.g., lithography optics, cleaning tanks) are prioritized, with no strict requirements on hydroxyl content .

‌2. Monocrystalline Silicon Growth‌

• Quartz crucibles, as core containers, directly impact silicon purity. Impurities like aluminum, sodium, and potassium must be controlled at ppm levels .

‌3. Semiconductor Equipment Materials‌

• Synthetic quartz glass substrates for semiconductor photomasks demand high purity, low thermal expansion coefficients, and exceptional optical uniformity .

‌Ⅱ. Optical Field‌
‌1. High-Precision Optical Components‌

• Transparent synthetic quartz ingots are used in laser optics, UV/IR lenses, and prisms, leveraging their superior UV transmittance and near-zero thermal expansion .

‌2. Optical Communication Technology‌

• Synthetic quartz materials are applied in fiber-optic components (e.g., preforms, couplers) to ensure low signal loss and high environmental durability .

‌3. Core Components in Lithography Systems‌

• Lenses, mirrors, and other optics in lithography machines require synthetic quartz glass with ultra-low metal impurities (<1 ppb) and sub-nanometer surface roughness .
