Abstract:
1. A method of forming a semiconductor device comprising: providing a substrate including a semiconducting layer overlying an insulating layer; forming a gate structure atop a channel region of the semiconducting layer; removing portions of the semiconducting layer to provide exposed portions of the insulating layer, wherein a remaining portion of the semiconducting layer provides a semiconducting body underlying the gate structure that includes the channel region; forming dielectric regions on the exposed portions of the insulating layer, wherein the dielectric regions abut the semiconducting body; removing a portion of the dielectric regions, wherein a remaining portion of the dielectric region remains in direct physical contact with a drain dopant region of the semiconducting body, the drain dopant region being in direct physical contact with a first end of the channel region; forming a schottky barrier region as a source region on the portion of the semiconducting body that is opposite the drain dopant region, said schottky barrier region is in direct physical contact with a second end of the channel region; and forming a drain contact to the drain dopant region, wherein the drain contact to the drain dopant region is present overlying the remaining portion of the dielectric region and is in direct physical contact with a sidewall of the drain dopant region of the semiconducting body.
