  • Patent number: 9543398
    Abstract: A semiconductor switching device includes a first load terminal electrically connected to source zones of transistor cells. The source zones form first pn junctions with body zones. A second load terminal is electrically connected to a drain construction that forms second pn junctions with the body zones. Control structures, which include a control electrode and charge storage structures, directly adjoin the body zones. The control electrode controls a load current through the body zones. The charge storage structures insulate the control electrode from the body zones and contain a control charge adapted to induce inversion channels in the body zones in the absence of a potential difference between the control electrode and the first load electrode.
