Zusammenfassung:A power semiconductor device includes a substrate having an upper surface and a lower surface. A source region of first conductivity is formed within a well region of second conductivity. The source region is provided proximate to the upper surface of the substrate. The well region has a non-polygon design. A gate electrode overlies the upper surface of the substrate. A drain electrode is provided proximate to the lower surface of the substrate.
