Patent ID: 7414290

Claim:
A double gate transistor comprising: a substrate; a first electrically insulating layer over the substrate; a second electrically insulating layer over the first electrically insulating layer, the first electrically insulating layer and the second electrically insulating layer forming a fin over the substrate; a first gate dielectric at a first side of the fin; a second gate dielectric at a second side of the fin; a first metal region adjacent to the first gate dielectric and having a first surface; a second metal region adjacent to the second gate dielectric and having a second surface; a first polysilicon region adjacent to the first metal region; and a second polysilicon region adjacent to the second metal region, wherein: the first electrically insulating layer has a third surface; the second electrically insulating layer has a fourth surface; and the first surface and the second surface lie between the third surface and the fourth surface.
