Abstract:
1. An NMOS (n-type metal-oxide-semiconductor) comprising: a P-substrate; an N-well on the P-substrate; an N-drift region on the N-well; an n+ drain on the N-drift region; a plurality of first contacts on the n+ drain arranged along a longitudinal direction; a P-body on the N-well; a source on the P-body, the source comprising a plurality of n+ doped regions and at least one p+ doped region arranged along the longitudinal direction; a plurality of second contacts on the plurality of n+ doped regions and the at least one p+ doped region, wherein the plurality of second contacts on the plurality of n+ doped regions and the at least one p+ doped region are separate from one another; a polygate on the P-body; and a gate oxide between the polygate and the source.
