Patent ID: 7986005

Claim:
A power semiconductor device, comprising: a semiconductor body comprising: a plurality of cells, each cell comprising: a body region of a first conductivity type; a source region of a second conductivity type which is arranged in the semiconductor body and which adjoins the body region for forming a pn-junction between the source region and the body region; and a drift region of the second conductivity type in contact with the body region, wherein the body region comprises a channel region between the source region and the drift region for forming therein a conductive channel between the source region and the drift region; a gate electrode arranged next to the body region; a floating electrode arranged between the gate electrode and the channel region of the body region; and a tunnelling dielectric layer arranged between the floating electrode and the body region, wherein the gate electrodes of the plurality of cells are connected to each other, and the source regions of the plurality of cells are connected to each other.
