Abstract
A semiconductor device includes a semiconductor mesa having source zones and at least one body zone forming first pn junctions with the source zones and a second pn junction with a drift zone. Electrode structures are provided on opposite sides of the semiconductor mesa, at least one of the electrode structures having a gate electrode configured to control a charge carrier flow through the at least one body zone. A separation region is arranged along an extension direction of the semiconductor mesa. In the separation region, the semiconductor mesa has a constricted portion that is partially or completely oxidized. Additional semiconductor device embodiments are described.
