Abstract
An integrated circuit device includes a semiconductor body fitted with a first electrode and a second electrode on opposite surfaces. A control electrode on an insulating layer controls channel regions of body zones for a current flow between the two electrodes. A drift section adjoining the channel regions comprises drift zones and charge compensation zones. A part of the charge compensation zones includes conductively connected charge compensation zones electrically connected to the first electrode. Another part includes nearly-floating charge compensation zones, so that an increased control electrode surface has a monolithically integrated additional capacitance Cin a cell region of the semiconductor device.
