High-Purity Fused Silica & Quartz Wafers: Material Synthesis & Sub-Nanometer Finishing
In high-frequency electronics, integrated quantum optics, and extreme ultraviolet (EUV) lithography systems throughout the Bristol and Bath high-tech corridor, optical substrates must reconcile extreme thermal gradients with atomic-scale structural homogeneity. Standard borosilicate and soda-lime substrates fail under thermal cycling above 450°C and introduce unacceptable RF dissipation. Our OEM factory produces custom fused silica quartz wafers utilizing vapor-phase axial oxidation of high-purity silicon tetrachloride (SiCl₄), alongside electric vacuum-arc fused natural crystalline quartz from the world's most concentrated silicon deposits in Donghai, Jiangsu.
The distinction between Synthetic Fused Silica (Type III / JGS1) and Fused Natural Quartz (Type II / JGS2) governs performance metrics in critical applications. Synthetic fused silica features virtually zero metallic trace impurities (total metal content < 0.5 ppm), completely eliminating absorption bands in the Deep Ultraviolet (DUV 193 nm to 260 nm) spectrum. It exhibits an isotropic refractive index variation (Δn) as tight as 1 × 10⁻⁶, zero bubble-inclusion classification according to DIN 3140 / ISO 10110 standards, and internal stress birefringence below 2 nm/cm. For high-temperature diffusion furnaces and CVD reactor components operating up to 1150°C, electric-fused quartz delivers elevated hydroxyl (OH) resistance and superior mechanical strength against devitrification.

Our wafer surface finishing leverages multi-stage planetary chemical-mechanical planarization (CMP) using ultra-fine ceria and colloidal silica slurries. Cleanroom wafer dicing utilizes Nd:YVO4 diode-pumped UV laser trepanning or high-precision resin-bonded diamond blades to achieve defect-free edge chamfers (≥ 45° safety bevels according to SEMI standards M1-0307). Laser scribing and SEMI standard orientation flats or notches (100, 111, or arbitrary angles) are executed to ± 0.05 mm accuracy. Each batch destined for cleanrooms in Bristol undergoes ultrasonic multi-bath mega-sonic deionized (DI) water washing (18.2 MΩ·cm resistivity) and is vacuum-sealed in nitrogen-purged polycarbonate wafer cassettes.
