1. Semiconductor Manufacturing
6-inch quartz wafers are widely used in semiconductor packaging, chip fabrication, and related fields, particularly in the production of:
- Memory chips (DRAM, NAND Flash)
- Analog/power devices (IGBT, MOSFET)
- Advanced sensors (MEMS, CMOS image sensors)
2. Optical Components
Due to their high optical transmittance and ultra-low CTE, quartz wafers are ideal for:
- Precision lenses (aspheric, microlens arrays)
- Optical filters (bandpass, dichroic)
- Waveguides (photonic ICs, fiber coupling elements)
3. MEMS (Micro-Electro-Mechanical Systems)
Quartz wafers serve as premium substrates for MEMS devices due to their dimensional stability and mechanical robustness, including:
- Microsensors (pressure, inertial, biosensors)
- Microactuators (RF switches, piezoelectric transducers)
- Resonators (5G filters, timing devices)
4. High-Temperature Poly-Si TFT-LCDs
Quartz wafers are critical in manufacturing high-performance displays, specifically:
- HTPS (High-Temperature Poly-Si) TFT backplanes
- Microdisplays (AR/VR, LCoS)
- Advanced LCD panels (OLED encapsulation substrates)
We provide end-to-end solutions:
1. Material Selection: JGS1/JGS2 quartz, synthetic fused silica
2. Precision Machining:
- Laser cutting (±5μm tolerance)
- Ultrasonic drilling (aspect ratio 10:1)
3. Surface Engineering:
- Nano-polishing (Ra<0.3nm)
- DUV/IR anti-reflection coatings
4. Quality Assurance:
- Class 10 cleanroom processing
- Full metrology reports (TTV, warp, bow)
1. Q: What are the advantages of 6-inch quartz wafers over smaller sizes in semiconductor manufacturing?
A: 6-inch (150mm) quartz wafers provide 56% more usable area than 4-inch wafers, significantly reducing edge exclusion losses and improving throughput for advanced packaging and MEMS production.
2. Q: How does quartz wafer purity (≥99.999%) impact high-temperature processes?
A: 5N purity quartz minimizes contamination risks in HTPS TFT and semiconductor annealing processes above 1000°C, ensuring consistent dielectric properties.
