Silicon Carbide - Structure, Properties, and Uses of SiC

08/04/2019· Silicon carbide also commonly known as Carborundum, is a compound of silicon and carbon. Silicon carbide is a semiconductor material as an emerging material for appliions in semiconductor devices. Silicon carbide was discovered by Pennsylvanian Edward Acheson in 1891. It is one of the most important industrial ceramic materials.

US6926926B2 - Silicon carbide deposited by high …

A SiC-based layer is deposited on a substrate having an electrical resistivity between about 1 and 100 Ω cm. The substrate is disposed in a process chaer. A gaseous mixture having a silicon-containing gas and a hydrocarbon-containing gas is flowed to the process chaer. A high-density plasma, having an ion density greater than about 10 11 ions/cm 3 is generated from the plasma.
