Abstract:
1. A silicon-on-insulator (SOI) device, comprising: a SOI substrate having an active area, wherein said SOI substrate comprises a semiconductor layer overlying an insulator layer; at least one gate structure comprising a gate dielectric layer and a gate electrode layer over said semiconductor layer of said active area; a source region and a drain region in said semiconductor layer of said active area and separated from each other; a dielectric layer resistant to silicidation with a bottom surface overlying a top surface of said semiconductor layer of said active area, wherein said dielectric layer resistant to silicidation is made of a material different from said gate dielectric layer; and a body contact region in said semiconductor layer of said active area and separated from said source region and said drain region by a region underlying said dielectric layer resistant to silicidation, wherein said body contact region is in contact with a metal-silicide layer.
