    摘要: A semiconductor device includes an insulator layer, a semiconductor layer, a first transistor, and a second transistor. The semiconductor layer is overlying the insulator layer. A first portion of the semiconductor layer has a first thickness. A second portion of the semiconductor layer has a second thickness. The second thickness is larger than the first thickness. The first transistor has a first active region formed from the first portion of the semiconductor layer. The second transistor has a second active region formed from the second portion of the semiconductor layer. The first transistor may be a planar transistor and the second transistor may be a multiple-gate transistor, for example.

    摘要: A semiconductor structure includes of a plurality of semiconductor fins overlying an insulator layer, a gate dielectric overlying a portion of said semiconductor fin, and a gate electrode overlying the gate dielectric. Each of the semiconductor fins has a top surface, a first sidewall surface, and a second sidewall surface. Dopant ions are implanted at a first angle (e.g., greater than about 7°) with respect to the normal of the top surface of the semiconductor fin to dope the first sidewall surface and the top surface. Further dopant ions are implanted with respect to the normal of the top surface of the semiconductor fin to dope the second sidewall surface and the top surface.
