Silicon carbide (SiC), also known as carborundum (/ ˌ k ɑːr b ə ˈ r ʌ n d əm /), is a hard chemical compound containing silicon and carbon. A wide bandgap semiconductor , it occurs in nature as the extremely rare mineral moissanite , but has been mass-produced as a powder and crystal since 1893 for use as an abrasive .
Silicon carbide is currently being used in the semiconductor industry already, due to the fact that it belongs to a family of materials called complementary metal–oxide–semiconductor compatible materials, as well as its reliability in fabrication of high-quality single crystal wafers. [1]
Silicon used in semiconductor device manufacturing is currently fabricated into boules that are large enough in diameter to allow the production of 300 mm (12 in.) wafers. Germanium (Ge) was a widely used early semiconductor material but its thermal sensitivity makes it less useful than silicon.

Wolfspeed, Inc. is an American developer and manufacturer of wide-bandgap semiconductors, focused on silicon carbide and gallium nitride materials and devices for power and radio frequency applications such as transportation, power supplies, power inverters, and wireless systems.
Wolfspeed is a leader in silicon carbide (SiC) products used in power applications. AMD produces advanced semiconductor chips for AI. Both have seen share-price declines this year as of December ...
A compound semiconductor is a semiconductor compound composed of chemical elements of at least two different species. These semiconductors form for example in periodic table groups 13–15 (old groups III–V), for example of elements from the Boron group (old group III, boron, aluminium, gallium, indium) and from group 15 (old group V, nitrogen, phosphorus, arsenic, antimony, bismuth).
Wolfspeed, which was formerly known as Cree, mainly manufactures wide-bandgap (WBG) semiconductors made from silicon carbide and gallium nitride. These chips can operate at higher voltages ...
