Abstract:
A method for forming a semiconductor device comprising the steps of:providing a body of semiconductor material having a first conductivity type and a first dopant concentration;forming a pedestal on the body of semiconductor material, the pedestal having a major surface;forming a doped region of the first conductivity type in the pedestal, wherein the doped region is spaced apart from the major surface;forming a gate structure on the major surface of the pedestal and overlying the doped region;forming a source region in the pedestal, wherein the source region is of a second conductivity type, and wherein the source region is vertically and laterally spaced apart from the doped region; andforming a drain region in the pedestal, wherein the drain region is of the second conductivity type, and wherein the drain region is spaced apart from the source region to form a channel region between the drain region and the source region, and wherein the drain region is vertically and laterally spaced apart from the doped region.
