Polished R-plane Sapphire Wafers for SOS

R-plane Sapphire (1-102), 57.6 degrees to C-plane, is the preferred material for Silicon-on-Sapphire used in semiconductor, microwave and pressure transducer applications.

Typical applications for Silicon on Sapphire wafers include:

• Fabrication of active topside Silicon-based devices
• Fabrication of topside laser devices
• Backside polishing of the SOS wafer to fabricate an optical device on the Silicon side
• Etching off the Silicon side to utilize the Sapphire as a SEMI standard wafer, or wafer carrier
