Classification: CPC H | IPC H

Claim 12:
13. A method of fabricating a semiconductor device, the method comprising:
providing a semiconductor-on-insulator substrate comprising, stacked from the bottom upward, a lower substrate, a buried insulator layer and a semiconductor layer, wherein active regions surrounded by trench isolation structures are formed in the semiconductor layer;
forming a gate electrode layer over the semiconductor layer, the gate electrode layer extending from the active regions to the trench isolation structures;
forming a source region and a drain region in the active regions that are on opposing sides of the gate electrode layer, wherein at least one end portion of the gate electrode layer laterally spans over interfaces of the active regions and the trench isolation structures toward the source region and/or the drain region; and
forming a body contact region in the source region, wherein the body contact region is in contact with the gate electrode layer.
