Fused silica is generally preferred for deep-UV optics, high thermal stability, and low thermal expansion. Borosilicate glass offers a practical balance of optical performance, thermal resistance, and cost, while quartz glass selection depends on its material structure, purity, and grade.
Ultra-flat silicon wafers offer tighter control of thickness variation, wafer geometry, and surface consistency than standard wafers specified for less demanding processes. They are most useful when lithography, wafer bonding, thinning, or precision alignment requires a narrower process window.
A thermal oxide silicon wafer has a deliberately grown silicon dioxide (SiO₂) layer on its surface, while a bare silicon wafer has no intentionally formed oxide layer. The choice depends on electrical insulation, surface chemistry, device structure, and subsequent fabrication requirements.
