Abstract:
A MOSFET device comprising: a structural region, made of a semiconductor material having a first type of conductivity, which extends between a first side and a second side opposite to the first side along an axis; a body region, having a second type of conductivity opposite to the first type, which extends in the structural region starting from the first side; a source region, having the first type of conductivity, which extends in the body region starting from the first side; a gate region, which extends in the structural region starting from the first side, traversing entirely the body region; and a shielding region, having the second type of conductivity, which extends in the structural region between the gate region and the second side. The shielding region is an implanted region self-aligned, in top view, to the gate region.
