Patent ID: 7230264

Claim:
A semiconductor device, comprising: a first transistor comprising: a semiconductor substrate; control electrode overlying the semiconductor substrate; a first current electrode overlying the semiconductor substrate and adjacent a portion of a first side of the control electrode, the first current electrode comprised of a first predetermined semiconductor material; a second current electrode overlying the semiconductor substrate and adjacent a portion of a second side of the control electrode, the first current electrode and the second current electrode forming a channel underlying the control electrode, all of the channel comprising a same material and of different material than the semiconductor substrate, the second current electrode having a second predetermined semiconductor material that is different from the first predetermined semiconductor material, the first predetermined semiconductor material being chosen to optimize bandgap energy of the first current electrode, and the second predetermined semiconductor material being chosen to optimize strain of the channel; and a second transistor laterally adjacent the first transistor and separated by an isolation material, the second transistor comprising: a control electrode overlying the semiconductor substrate; a first current electrode overlying the semiconductor substrate and adjacent a portion of a first side of the control electrode; and a second current electrode overlying the semiconductor substrate and adjacent a portion of a second side of the control electrode, the first current electrode and the second current electrode forming a channel underlying the control electrode, the channel comprising entirely a same material that is different from the same material of the first transistor.
