Abstract

A MOS-gated power device includes a plurality of elementary functional units, each elementary functional unit including a body region of a first conductivity type formed in a semiconductor material layer of a second conductivity type having a first resistivity value. Under each body region a respective lightly doped region of the second conductivity type is provided having a second resistivity value higher than the first resistivity value.
