Patent ID: 7550333

Claim:
A method of forming a device comprising: forming a semiconductor body on an insulating layer of a substrate, said semiconductor body having a top surface opposite a bottom surface formed on said insulating layer and a pair of laterally opposite sidewalls wherein the laterally opposite sidewalls include a tapered portion such that the distance between said laterally opposite sidewalls is less at the bottom surface of said semiconductor body than at the top surface of said semiconductor body; forming a gate dielectric layer on and in direct contact with said top surface of said semiconductor body and on said sidewalls of said semiconductor body, wherein the composition of said gate dielectric layer formed on said top surface is the same composition as said gate dielectric layer on said sidewalls; forming a gate electrode on said gate dielectric layer on said top surface of said semiconductor body and adjacent to said gate dielectric layer on said sidewalls of said semiconductor body; and forming a pair of source/drain regions in said semiconductor body on opposite sides of said gate electrode.
