Abstract

A MOSFET device design is provided that effectively addresses the problems arising from the parasitic bipolar transistor that is intrinsic to the device. The MOSFET device comprises: (a) a body region; (b) a plurality of body contact regions; (c) a plurality of source regions; (d) a plurality of drain regions; and (d) a gate region. In plan view, the source regions and the drain regions are arranged in orthogonal rows and columns, and at least a portion of the body contact regions are bordered by four of the source and drain regions, preferably two source regions and two drain regions.
