Silicon carbide semiconductor devices with a regrown contact layer

摘要

Silicon carbide semiconductor devices having regrown layers and methods of fabricating the same in a self-aligned manner. According to one aspect of the invention, the method includes growing at least one layer of silicon carbide on a substrate, removing the device from a growth chamber to perform at least one processing step, and regrowing another layer of silicon carbide on the at least one layer. According to one embodiment of the invention, the regrown layer may be a heavily doped contact layer for the formation of low resistivity ohmic contacts.
