Abstract:
A power semiconductor device is disclosed. The device includes a semiconductor body coupled to a first load terminal structure and a second load terminal structure, a first cell and a second cell. A first mesa is included in the first cell, the first mesa including: a first port region and a first channel region. A second mesa included in the second cell, the second mesa including a second port region. A third cell is electrically connected to the second load terminal structure and electrically connected to a drift region. The third cell includes a third mesa comprising: a third port region, a third channel region, and a third control electrode.
