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.

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.
Quartz wafers play a critical role in advanced technology sectors, as detailed below:
| Application Field | Specific Uses | Advantages of Quartz Wafers |
| Semiconductor Manufacturing | - Photomask substrates - Etching process carriers - CMP polishing pads - Temporary bonding wafers | High flatness, low thermal expansion, plasma corrosion resistance |
| Optoelectronic Devices | - Laser windows - Optical filter substrates - IR sensor substrates - Photodetector packaging | High UV-IR transmittance, low absorption loss |
| MEMS/NEMS | - MEMS structural layers - Precision sensor diaphragms - Nanoimprint templates | Ultra-smooth surface, high rigidity, chemical stability |
