Zusammenfassung: | An RC IGBT includes: an active region with separate IGBT and diode sections; a semiconductor body forming a part of the active region; a first load terminal and control terminal at a first side of the body and a second load terminal at a second side, the control terminal including a control terminal finger that laterally overlaps, in the active region, with the diode section. Control trenches extending into the semiconductor body along a vertical direction have a control trench electrode electrically connected to the control terminal for controlling a load current between the load terminals in the IGBT section. At least one control trench extends into both IGBT and diode sections. The electrical connection between the control trench electrode of that control trench and the control terminal is established at least based on an electrically conductive member arranged, in the diode section, in contact with the control terminal finger. |
