Patent ID: 6853020

Claim:
A semiconductor device, comprising: a substrate; an insulating layer formed on the substrate; a fin formed on the insulating layer; a first gate formed on the insulating layer and disposed on a first side of the fin, the first gate comprising a conductive material, wherein at least a portion of the first gate is doped with an n-type dopant, wherein a region of the first gate located near the fin has a higher concentration of the n-type dopant than an area located further away from the fin; and a second gate formed on the insulating layer and disposed on a second side of the fin opposite the first side, the second gate comprising a conductive material, wherein at least a portion of the second gate is doped with a p-type dopant, wherein a region of the second sate located near the fin has a higher concentration of the p-type dopant than an area located further away from the fin.
