\"T\u1ea5mThe 2-inch quartz wafer is a semiconductor-grade substrate made from high-purity silicon dioxide (SiO\u2082). It achieves micron-level flatness through precision processing techniques such as CNC cutting and laser polishing. These wafers comply with SEMI standards and support customization in dimensions and thickness (\u00b10.02 mm tolerance), making them suitable for optoelectronics, MEMS (Micro-Electro-Mechanical Systems), and semiconductor packaging.<\/p>\n

Fuyao provides customized production for non-standard geometries, including freeform shapes, graded thickness, and advanced surface treatments such as Anti-Reflective (AR) coatings and hydrophobic films. Full-process quality control ensures total thickness variation (TTV) <0.005 mm and surface roughness Ra <1.5 nm. Small-batch prototyping (minimum 10 units) and rapid delivery options are available for time-sensitive projects.<\/p>\n
