Patent ID: 6905919

Claim:
A method of forming a metal oxide semiconductor field effect transistor (MOSFET) device on a semiconductor substrate, comprising the steps of: providing a semiconductor substrate of a first conductivity type; forming a silicon on insulator (SOI) layer on said semiconductor substrate; forming an insulator filled, shallow trench isolation (STI) region in the silicon component of the SOI layer, with depth of said STI terminating at the top surface of the insulator component of said SOI layer; forming a gate insulator layer on surface of said silicon component of said SOI layer; forming a conductive gate structure on said gate insulator layer, and on a portion of said STI region; forming a body contact region entirely in a first portion of said silicon component of said SOI region; and forming a source/drain region in a second portion of said silicon component of said SOI layer, wherein said second portion of said silicon component of said SOI layer is separated from said first portion of said silicon component of said SOI layer by said STI region.
