Patent ID: 6858478

Claim:
A method of forming a semiconductor device comprising: forming an oxidation resistant film on a semiconductor body film formed on an insulating substrate; patterning said oxidation resistant film and said semiconductor body film to form an oxidation resistant mask a semiconductor body having a top surface opposite a bottom surface formed on said insulating film, and a first and a second laterally opposite sidewalls, wherein said oxidation resistant mask is formed on said top surface of said semiconductor body; growing an oxide on the laterally opposite sidewalls of said semiconductor body while said top surface of said semiconductor body is covered by said oxidation resistant mask; removing said oxidation resistant mask from said top surface of said semiconductor body; depositing a dielectric film adjacent to said grown oxide on said sidewalls of said semiconductor body and on the top surface of said semiconductor body; and forming a gate electrode above said gate dielectric on said top surface of said semiconductor body and adjacent to said deposited oxide on said laterally opposite sidewalls of said semiconductor body.
