Abstract
A metal-oxide semiconductor field effect transistor (MOSFET), a method of manufacturing the MOSFET and a power supply incorporating at least one such MOSFET. In one embodiment, the MOSFET includes: (1) a substrate having an epitaxial layer underlying a gate oxide layer, a portion of the epitaxial layer being a gate region of the MOSFET, (2) an N-type drift region located in the epitaxial layer laterally proximate the gate region and (3) source and drain regions located in the epitaxial layer and laterally straddling the gate and drift regions.
