Abstract
A field-effect semiconductor device includes a semiconductor body having a first semiconductor region of a first conductivity type, a first side, an edge delimiting the semiconductor body in a direction substantially parallel to the first side, an active area, and a peripheral area arranged between the active area and the edge. A first metallization is arranged on the first side, and a second metallization is arranged opposite the first metallization and in Ohmic connection with the first semiconductor region. In the active area, the semiconductor body further includes: a plurality of drift portions of the first conductivity type alternating with compensation regions of a second conductivity type, the drift portions being in Ohmic connection with the first semiconductor region, the compensation regions being in Ohmic connection with the first metallization and having in a vertical direction perpendicular to the first side a vertical extension.
