6 inch quartz wafer details

​​6inch Heat-Resistant Transparent Monocrystalline Quartz Crystal Substrate for SAW Devices​​

The 6-inch quartz wafer (150mm diameter) is fabricated from high-purity quartz glass (purity ≥99.999%) with thickness ranging from 50-500μm. Surface roughness is controlled to Ra ≤0.5nm through CMP (Chemical Mechanical Polishing). The manufacturing process includes: ​​

· Raw Material Purification​​: Extraction of electronic-grade silicon from quartz sand via chlorination and reduction processes, achieving 99.9999% purity. ​​

· Single-Crystal Growth​​: Cultivation of single-crystal silicon rods using the Czochralski (CZ) method, with defect density <1 defect/cm². ​​

· Cutting and Processing​​: Slicing silicon rods into 150mm wafers via multi-wire sawing, followed by double-sided polishing and laser etching to ensure thickness tolerance ≤±15μm.
