Last year, according to estimates made by wafer maker Cree, the global market for silicon carbide devices topped US $100 million for the first time. What’s more, SiC wafer manufacturers have steadily reduced the defects in the material while increasing the wafer size, thus driving down the prices of SiC devices. And over the last few years, they’ve been joined by the first commercially available SiC transistors, enabling a new range of SiC-based power electronics. ![]() Simple SiC diodes have already started to supplant silicon devices in some applications. Devices made from silicon carbide (SiC)-a faster, tougher, and more efficient alternative to straight silicon-are beginning to take off. But soon this ubiquitous substance will have to share the spotlight. Silicon has long been the semiconductor of choice for such power electronics.
