Patent ID: 8829609

Claim:
An insulated gate semiconductor device comprising: a semiconductor body having a front side and a back side opposite to one another; a drift region, which extends in the semiconductor body and has a first type of conductivity and a first doping value; a body region having a second type of conductivity, which extends in the drift region and faces the front side of the semiconductor body; a charge carrier region that is a source of charge carriers having the first type of conductivity, the body region housing the charge carrier region; a buried region having the second type of conductivity, which extends in the drift region at a distance from the body region and is at least partially aligned to the body region along a first direction orthogonal to the front side and to the back side; a collector region positioned adjacent to the back side of the semiconductor body; and a first gate terminal extending from the front side of the semiconductor body into the drift region, the first gate terminal being laterally spaced apart from the buried region, in a second direction parallel to the front side of the semiconductor body, by a first portion of the drift region.
