    摘要: A semiconductor device with a dynamic gate drain capacitance. One embodiment provides a semiconductor device. The device includes a semiconductor substrate, a field effect transistor structure including a source region, a first body region, a drain region, a gate electrode structure and a gate insulating layer. The gate insulating layer is arranged between the gate electrode structure and the body region. The gate electrode structure and the drain region partially form a capacitor structure including a gate-drain capacitance configured to dynamically change with varying reverse voltages applied between the source and drain regions. The gate-drain capacitance includes at least one local maximum at a given threshold or a plateau-like course at given reverse voltage.

    摘要: 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 CZGD in a cell region of the semiconductor device.
