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.
