Patent ID: 8188541

Claim:
A vertical MOSFET comprising: a semiconductor body having a substantially planar first surface defining a source and a substantially planar second surface defining a drain, said first surface and said second surface being substantially parallel and not co-planar, wherein said source is electrically coupled to a source electrode associated with said first surface and said drain is electrically coupled to a drain electrode associated with said second surface: a gate comprising a conductive material and an insulating layer which electrically isolates said conductive material from said body formed proximate said second surface; and a via formed within said semiconductor body at least partially between said first surface and said second surface and coupled to said gate, wherein said via includes a conductive material and an insulating layer which electrically isolates the conductive material from said body; wherein said vertical MOSFET comprises a plurality of MOSFET cells having their sources, drains, and gates electrically connected to said source, drain and gate, respectively, of said vertical MOSFET.
