Inseto specialize in supplying silicon on Sapphire wafer (SOS) comprising Kr grown Sapphire and EPI Si layers with tightly controlled thicknesses with excellent TTV, and flatness values. Silicon on Sapphire wafer sizes range from 3" to 200mm and are available in small lot sizes, ideal for research and development applications.

SOS wafers are closely related to SOI and are used in the fabrication of high frequency devices such as RFIC's, RF Amplifiers and RF Switches, where the low loss of the substrates allows dense design rules without leakage and performance issues. The high temperature conductance of the Sapphire substrates, assists in thermal management of the device.

R plane Sapphire has a close lattice match to (100) Si and when used to fabricate RF devices, low power consumption and superior radiation hardness exceed what is possible with other SOI technologies. SoS wafers can have a wide range of Si thicknesses grown on them, and is also a convenient way to make smaller quantities of SOI wafer for photonics use.

High-quality SoS Wafers are shipped and used worldwide by University and Industrial Research, Manufacturing and equipment manufacturers. SOS wafers can be purchased online via the Inseto Wafer Store.
