Patent ID: 7821063

Claim:
A method for forming a semiconductor device, comprising the steps of: providing a substrate having a major surface, wherein the substrate comprises a first conductivity type; forming a pedestal structure on a portion of the major surface; forming a conductive material along a side surface of the pedestal structure to define an edge of a first conduction electrode of the semiconductor device; forming a first doped region of a second conductivity type in the major surface adjacent the first conduction electrode, wherein a portion of the first doped region forms a channel region when the semiconductor device is in operation; forming second region of the first conductivity type in the first doped region; and forming a localized region of doping of the first conductivity in the substrate 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.
