2 inch Precision Processed Quartz Glass Wafer DSP SSP Diameter 50.8mm

​2-inch quartz wafers are semiconductor-grade substrates manufactured from high-purity silicon dioxide (SiO₂), achieving micron-level flatness through precision processing techniques such as CNC cutting and laser polishing. These wafers adhere to SEMI standards and support customization in dimensions and thickness (±0.02 mm tolerance), catering to applications in optoelectronics, MEMS (Micro-Electro-Mechanical Systems), and semiconductor packaging.

ZMSH specializes in ​​customized production​​ of non-standard geometries (e.g., non-standard apertures, graded thickness) and advanced surface treatments (Anti-Reflective (AR) coatings, hydrophobic films) to address unique client requirements. Rigorous ​​full-process quality control​​ ensures compliance with stringent specifications, from raw material testing (hydroxyl content <50 ppm) to final AOI inspection, guaranteeing Total Thickness Variation (TTV) <0.005 mm and surface roughness Ra <1.5 nm. For time-sensitive projects, ZMSH offers ​​rapid response services​​, including small-batch prototyping (minimum 10 units) and expedited delivery (72-hour turnaround) to meet urgent demands.

Specification for 2inch quartz wafer

​​Key Characteristics​​ of 2inch quartz wafer

1. ​​Optical Excellence​​

​​· Broad-Spectrum Transmittance​​: >90% transmittance in the ultraviolet (185–3500 nm) range, with superior performance in the short-wave UV band (185 nm) compared to conventional glass.

​​· Low Thermal Expansion​​: Coefficient of thermal expansion (CTE) of 0.52×10⁻⁶/°C (5–35°C), withstanding long-term temperatures up to 1100°C and short-term exposure to 1450°C.

​​2. Mechanical & Chemical Stability​​

· ​​High Strength​​: Flexural strength 2–3× that of standard glass, Mohs hardness of 7.

· ​​Corrosion Resistance​​: 30× higher acid resistance than ceramics, ideal for harsh chemical environments.

3. ​​Electrical Insulation​​

· Resistivity exceeding 10¹⁸ Ω·cm, with low dielectric loss at high frequencies, making it suitable for RF circuits and sensors.

​​Core Applications​​ of 2inch quartz wafer
