Abstract:
A power semiconductor device includes a semiconductor body coupled to first and second load terminal structures, and first and second cells each configured for controlling a load current and electrically connected to the first load terminal structure and to a drift region. A first mesa in the first cell includes a port region electrically connected to the first load terminal structure, and a first channel region coupled to the drift region. A second mesa included in the second cell includes a port region electrically connected to the first load terminal structure, and a second channel region coupled to the drift region. The mesas are spatially confined in a direction perpendicular to a direction of the load current by an insulation structure, and have a total extension of less than 100 nm in that direction. The first channel region includes an inversion channel. The second channel region includes an accumulation channel.

Claim (Index 15):
The power semiconductor device of  claim 1 , wherein the semiconductor body further comprises a plateau region having the second conductivity type and being arranged between the second channel region and the semiconductor drift region and extending deeper into the semiconductor body than the second mesa, wherein, in a section arranged deeper than the second mesa, the plateau region extends laterally from the second mesa towards the first mesa, and wherein a lateral extension of the section is at least 50% of a distance between the first and second mesas.
