Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 8:
9. A semiconductor device, comprising:
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;
a gate electrode layer formed over the semiconductor layer, the gate electrode layer extending from the active regions to the trench isolation structures, wherein the gate electrode layer comprises a base gate section and an extended gate section;
a source region and a drain region respectively formed in the active regions that are on opposing sides of the base gate section, 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
a body contact region straddling over the extended gate section and remote from the base gate section,
wherein the body contact region is formed in the source region and brought into contact with the gate electrode layer.
