Silicon carbide (SiC), or carborundum, is a semiconductor containing silicon and carbon with the chemical formula SiC. SiC is used in semiconductor electronics devices operating at high temperatures, high voltages, or both. SiC is also one of the important LED components, it is a popular substrate for growing GaN devices, and it also serves as a heat spreader in high-power LEDs.

SiC Applications
Silicon carbide (SiC) crystals have unique physical and electronic properties. Silicon Carbide based devices have been used for short wavelength optoelectronic, high temperature, radiation resistant applications. The high-power and high-frequency electronic devices made with SiC are superior to Si and GaAs-based devices. Below are some popular applications of SiC substrates.
