With 30 years of experience in crystal quartz processing, we specialize in producing large, thin wafers conforming to SEMI standards. We can fabricate wafers up to 8 inches in diameter with polishing capabilities down to 0.1mm for 4-inch quartz wafers.
X, Y, Z, AT, ST, BT, CT, ET, DT, GT, NT, FC, SC, IT, and custom orientations as required.
We are piezoelectric wafer specialists with 30 years of experience in single crystal quartz processing. We also work with LiNbO₃, LiTaO₃, quartz glass, LGS, and CTGS materials, with particular expertise in AT, SC, and IT cuts with superior angle precision.
Yes, we fabricate according to customer specifications and provide technical guidance for optimal wafer selection. Standard wafers are also available from stock.
We can ship using your preferred courier account (DHL, FedEx, UPS) or arrange shipping with our discounted international carrier rates.
We use specialized packaging with buffer sponge and vacuum sealing. Follow our acceptance check procedure: inspect outer carton condition, photograph before opening, handle in clean room environment, and immediately document any damage without removing from packaging.
Factory inspections are welcome for large quantity purchases and long-term partnerships. We also offer videoconferencing for remote discussions.
- Handle with care and check outer carton condition upon receipt
- Photograph packaging before opening for documentation
- Open vacuum packages only in clean room environments
- Document any damage immediately without removing products from packaging
