Abstract
A semiconductor device comprises a semiconductor layer, a body region of a first conductivity type formed in the semiconductor layer and extending from a first surface of the semiconductor layer, a first region of a second conductivity type formed in the body region, and a second region of the first conductivity type formed in the body region. The first region extends from the first surface of the semiconductor layer and provides a current electrode region of the semiconductor device. The second region surrounds the first region. The doping concentration of the first conductivity type in the second region is greater than a doping concentration of the first conductivity type in the body region.
