What is Silicon Wafer or Silicon Substrate? What is it used for?

WebbFUSED SILICA WAFER. “Fused Silica” or “Fused Quartz” which is the amorphous phase of quartz (SiO2). When contrasted to borosilicate glass, fused silica has no additives; hence it exists in its pure form, SiO2. Fused silica has a higher transmission in the infrared and ultraviolet spectrum when compared to normal glass.
