Abstract
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 facing the front side of the semiconductor body; a source region, which extends in the body region and has the first type of conductivity; and a buried region having the second type of conductivity, which extends in the drift region at a distance from the body region and at least partially aligned to the body region in a direction orthogonal to the front side and to the back side.
