Abstract
In an example, a silicon carbide device includes a silicon carbide body. The silicon carbide body includes a central region and a peripheral region surrounding the central region. The central region includes a source region of a first conductivity type. The peripheral region includes a doped region of a second conductivity type. A stripe-shaped gate electrode extends through the central region and into the peripheral region. A contiguous source metallization is formed on the central region and on an inner portion of the peripheral region. The contiguous source metallization and the source region form a first ohmic contact in the central region. The contiguous source metallization and the doped region form a second ohmic contact in the peripheral region.
