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 .

Hiroyuki Matsunami (松波弘之 born June 5, 1939) is a Japanese engineer, researcher and educator. He was awarded the IEEE Edison Medal in 2023 for his pioneering contributions to the development of the material silicon carbide and its applications in electronic power devices. [1]
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. The company was formerly named Cree, Inc. [1]
The high breakdown voltage of wide-bandgap semiconductors is a useful property in high-power applications that require large electric fields. Devices for high power and high temperature [5] applications have been developed. Both gallium nitride and silicon carbide are robust materials well suited for
Wilmington, Delaware, Jan. 27, 2025 (GLOBE NEWSWIRE) -- Allied Market Research published a report, titled, "Power Electronics Market by Device Type (Power Discrete, Power Module, and Power IC), Material (Silicon Carbide, Gallium Nitride, Sapphire, and Others), Application (Power Management, Uninterruptible Power Supply, Renewable, and Others), and End Use (Telecommunication, Industrial ...
Silicon carbide has a high thermal conductivity, and temperature has little influence on its switching and thermal characteristics. With special packaging, silicon carbide Schottky diodes can operate at junction temperatures of over 500 K (about 200 °C), which allows passive radiative cooling in aerospace applications. [5]
Silicon carbide charge is sublimated from the bottom of the chamber and deposited on the upper lid, which is cooler. The Lely method , also known as the Lely process or Lely technique , is a crystal growth technology used for producing silicon carbide crystals for the semiconductor industry .
