Custom 2inch 3inch 4inch 6inch 8inch 12inch Quartz Wafers Transparent Fused Silica Substrates

Custom 2inch 3inch 4inch 6inch 8inch 12inch Quartz Wafers Transparent Fused Silica Substrates

Quartz wafers are precision substrates made from high-purity synthetic quartz materials, widely used in semiconductors, optoelectronics, optics, and microelectromechanical systems (MEMS). ZMSH specializes in the R&D and production of quartz semiconductor materials, offering products such as quartz wafers, quartz optical windows, quartz tubes, and quartz boats, with quartz wafers as our core product line. We provide customizable solutions for 2-inch to 12-inch wafers, meeting specific requirements in dimensions, thickness, and surface treatments (polishing, coating, etc.).

ZMSH offer in-stock availability and custom machining services, ensuring high precision (e.g., TTV ≤5μm), superior flatness (Ra ≤1nm), and excellent high-temperature resistance (softening point up to 1730°C). Our products are widely applied in semiconductor manufacturing, photomask technology, sensors, and laser systems.

Data for 2-12inch quartz wafer

Key features of 2-12inch quartz wafer

The core properties of quartz wafers include:

• 1. High-Purity Material: Synthetic quartz (e.g., Suprasil or Corning 7980) with SiO₂ purity ≥99.99%, minimizing impurities in semiconductor processes.

•  

• 2. Thermal Stability: Low coefficient of thermal expansion (5.5×10⁻⁷/°C), withstanding temperatures exceeding 1000°C for extreme environments.

•  

• 3. Optical Performance: High transmittance from UV to IR wavelengths (e.g., >90% in deep UV), ideal for lithography and laser applications.

•  

• 4. Surface Precision: Ultra-precision polishing with surface roughness (Ra) ≤0.5nm and total thickness variation (TTV) ≤5μm.

•  

• 5. Size Range: Standard sizes from 2-inch, 4-inch, 6-inch, 8-inch to 12-inch, with support for custom specifications.

•  

• 6. Chemical Inertness: Resistant to strong acids (except HF), alkalis, and plasma etching, suitable for semiconductor processes.

•
