Patent ID: 7939865

Claim:
A metal-semiconductor field effect transistor (MESFET) comprising: a first silicon layer; an insulator layer formed on the first silicon layer; a second silicon layer formed on the insulator layer; a gate region, a source region, and a drain region formed in the second silicon layer; a first partial trench formed in the second silicon layer between at least a portion of the gate region and at least a portion of the source region, wherein the first partial trench stops short of the insulator layer; and a second partial trench formed in the second silicon layer between at least a portion of the gate region and at least a portion of the drain region, wherein the second partial trench stops short of the insulator layer; wherein the gate region comprises a gate silicide region, the source region comprises a source silicide region, and the drain region comprises a drain silicide region; wherein the first partial trench is formed between the gate silicide region and the source silicide region and extends into the second silicon layer past the gate silicide region; and wherein the second partial trench is formed between the gate silicide region and the drain silicide region and extends into the second silicon layer past the gate silicide region.
