Abstract:
In an embodiment, a power semiconductor device includes: a semiconductor body for conducting a load current between first and second load terminals; source and channel regions and a drift volume in the semiconductor body; a semiconductor zone in the semiconductor body and coupling the drift volume to the second load terminal, a first transition established between the semiconductor zone and the drift volume; a control electrode insulated from the semiconductor body and the load terminals and configured to control a path of the load current in the channel region; and a trench extending into the drift volume along an extension direction and including a field electrode. A cross-sectional area of the field electrode is smaller than a cross-sectional area of the control electrode in a plane parallel to the extension direction.

Claim (Index 20):
The power semiconductor device of  claim 19 , wherein the uncontacted region of the field electrode has a greater lateral extension than the uncontacted region of the control electrode.
