Patent ID: 8552477

Claim:
A semiconductor device formed on a SOI substrate which comprises a buried insulating layer and a semiconductor layer on the buried insulating layer, wherein a fin of semiconductive material having two opposing sides perpendicular to a main surface of the SOI substrate is provided in the semiconductor layer, the two opposing sides comprise a first side and a second side, said semiconductor device comprising: a source region and a drain region provided at other two opposing sides of the fin respectively; a channel region provided at a central portion of the fin; and a stack of gate dielectric and gate conductor provided at only the first side of the fin, where the gate conductor is isolated from the channel region by the gate dielectric, wherein the gate conductor extends laterally away from the first side of the fin in a gate extending direction parallel to the main surface of the SOI substrate; and wherein each of the source region and the drain region has a portion extending away from the second side of the fin in a source/drain extending laterally direction parallel to the main surface of the SOI substrate, the source/drain extending direction being opposite to the gate extending direction.
