Abstract:
1. A transistor device, comprising: a semiconductor body including a source region, a drift region, and a body region between the source region and the drift region; a source electrode electrically coupled to the source region; a gate electrode adjacent the body region and dielectrically insulated from the body region by a gate dielectric a field electrode adjacent the drift region, dielectrically insulated from the drift region by a field electrode dielectric, and electrically coupled to the source electrode; a drain region spaced apart from the field electrode by the drift region; and a rectifier element electrically coupling the field electrode to the source electrode; wherein the rectifier element comprises a first region and a second region, and one of the first region and second region is connected to the source electrode, and the other of the first region and second region is only connected to the field electrode.
