Patent ID: 8519473

Claim:
A vertical transistor component, comprising: a semiconductor body with a first surface and a second surface; a drift region; at least one source region and at least one body region arranged between the drift region and the first surface, wherein the body region is arranged between the source region and the drift region; at least one gate electrode arranged adjacent to the body region, and a gate dielectric arranged between the gate electrode and the at least one body region; a drain region arranged between the drift region and the second surface; a source electrode electrically contacting the at least one source region, electrically insulated from the gate electrode and arranged on the first surface; a drain electrode electrically contacting the drain region and arranged on the second surface; at least one gate connection electrode which is electrically insulated from the semiconductor body by a dielectric layer, is arranged in a trench through the semiconductor body, extends to the second surface, and is electrically connected with the at least one gate electrode; wherein the at least one source region and the at least one body region are arranged in an active area of the semiconductor body, and wherein the at least one gate connection electrode at least partially surrounds the active area and wherein the dielectric layer completely surrounds the active area through the semiconductor body.
