Patent ID: 7271446

Claim:
A thin channel silicon-on-insulator device comprising: a substrate having a layer of semiconducting material atop an insulating layer; a gate region atop said layer of semiconducting material; a doped conformal oxide film having at least a first portion that is in direct contact with a sidewall of said gate region and a second portion that is located directly atop a portion of said layer of semiconducting material, wherein said conformal oxide layer has a thickness ranging from about 2 nm to about 20 nm; a set of spacers located on the second portion of said doped conformal oxide film adjacent to said gate region; a raised source/drain region on either side of said gate region, where said raised source/drain region are separated from said gate region by said set of spacers and wherein an edge portion of said raised source/drain region is in direct contact with an edge portion of said doped conformal oxide that is located on said layer of said semiconductor material; and an extension region in said layer of semiconducting material, said extension region is directly beneath said second portion of the doped conformal oxide film and contains dopant species outdiffused from said doped conformal oxide film.
