Abstract

A silicon on insulator (SOI) substrate includes a layer of silicon carbide beneath an insulating layer on which semiconductor devices are formed. The silicon carbide layer has a high thermal conductivity and provides beneficial dissipation of thermal energy generated by the devices. The SOI substrate may be formed by a bonding method. SOI MOSFET devices using the SOI substrate are also disclosed.
