Abstract:
An IGBT having a barrier region is presented. A power unit cell of the IGBT has at least two trenches that may both extend into the barrier region. The barrier region may be p-doped and vertically confined, i.e., in and against the extension direction, by means of the drift region. The barrier region can be electrically floating.

Claim (Index 23):
An IGBT, comprising:\n a semiconductor body coupled to a first load terminal and a second load terminal of the IGBT and comprising a drift region configured to conduct a load current between the first and the second load terminals, the drift region comprising dopants of a first conductivity type; a power unit cell comprising:\n a control trench having a control trench electrode and a further trench having a further trench electrode; \n an active mesa comprising a source region with dopants of the first conductivity type and electrically connected to the first load terminal and a channel region with dopants of a second conductivity type, the channel region separating the source region and the drift region, wherein, in the active mesa, at least a respective section of each of the source region, the channel region and the drift region are arranged adjacent to a sidewall of the control trench, and wherein the control trench electrode is configured to receive a control signal from a control terminal of the IGBT and to control the load current in the active mesa; and \n an electrically floating semiconductor barrier region in the semiconductor body and comprising dopants of the second conductivity type, the barrier region laterally overlapping with both an entire width of the active mesa and a bottom of the further trench.
