Abstract:
1. A semiconductor device, comprising: a semiconductor material having a major surface, wherein the semiconductor material comprises a first conductivity type; a control electrode formed in spaced relationship with the semiconductor material; a body region of a second conductivity type formed in the major surface adjacent the control electrode, wherein a portion of the body region forms a channel region when the semiconductor device is in operation; a source region of the first conductivity type formed in the body region; and a localized region of doping of the first conductivity type formed in the semiconductor material in proximity to a drain edge of the channel region, wherein the localized region of doping is confined both vertically and horizontally adjacent the major surface, and wherein the localized region of doping has a dopant concentration at least five times greater than a dopant concentration of a portion of the semiconductor material, and wherein the portion of the semiconductor material is adjacent the major surface and adjacent to the localized region of doping.
