Abstract
A diode is integrated on a semiconductor chip having anode and cathode surfaces opposite to each other. The diode comprises a cathode region extending inwardly from the cathode surface, a drift region extending between the anode surface and the cathode region, and a plurality of anode regions extending from the anode surface in the drift region. The diode further comprises a cathode electrode coupled with the cathode region, and an anode electrode that contacts one or more contacted anode regions of said anode regions and is electrically insulated from one or more floating anode regions of the anode regions. The diode is configured so that charge carriers are injected from the floating anode regions into the drift region in response to applying of a control voltage exceeding a threshold voltage.
