Introduction
Fused silica wafers are thin sheets made of high-purity quartz crystals that can oscillate freely and exhibit extremely high stability and accuracy in terms of physical properties. In the production process of semiconductor chips, quartz wafers are mainly used in circuits such as clocks, oscillators, and filters. The application of quartz wafer is indispensable in synchronous data transmission, beat control, and other aspects. In addition, quartz wafers can also be used as optical windows or acoustic filters etc. in various electronic devices.
Size: 2 inch, 3 inch, 4 inch, 5 inch, 6 inch, 8 inch, 10 inch, 12 inch. Other size is customized.
Thickness: 0.5mm, 1mm, 2mm, 3mm, 4mm, 6mm. Other thickness is customized.
