Patent ID: 8455938

Claim:
A semiconductor device, comprising a semiconductor-on-insulator (SeOI) structure, comprising: a substrate; an insulating layer on the substrate; and a semiconductor layer on the insulating layer, wherein a first field-effect-transistor (FET) is formed therein, and further wherein the first FET comprises; a channel region in the substrate; a dielectric layer formed at least partially from a part of the insulating layer of the semiconductor-on-insulator structure; and a gate formed at least partially from a first part of the semiconductor layer of the semiconductor-on-insulator structure; and a second FET formed in the semiconductor-on-insulator structure, the structure comprising a channel region and source and drain regions made of a second part of the semiconductor layer of the semiconductor-on-insulator structure; wherein the first part of the semiconductor layer of the SeOI structure and the second part of the semiconductor layer of the SeOI structure at least partially overlap each other.
