    摘要： Generally, the present disclosure is directed to methods for forming embedded stressor regions in semiconductor devices such as transistor elements and the like. One illustrative method disclosed herein includes forming a first material in first cavities formed in a first active area adjacent to a first channel region of a semiconductor device, wherein the first material induces a first stress in the first channel region. The method also includes, among other things, forming a second material in second cavities formed in a second active area adjacent to a second channel region of the semiconductor device, wherein the second material induces a second stress in the second channel region that is of an opposite type of the first stress in the first channel region, and wherein the first and second cavities are formed during a common etch process.

    摘要： In a P-channel transistor comprising a high-k metal gate electrode structure, a superior dopant profile may be obtained, at least in the threshold adjusting semiconductor material, such as a silicon/germanium material, by incorporating a diffusion blocking species, such as fluorine, prior to forming the threshold adjusting semiconductor material. Consequently, the drain and source extension regions may be provided with a high dopant concentration as required for obtaining the target Miller capacitance without inducing undue dopant diffusion below the threshold adjusting semiconductor material, which may otherwise result in increased leakage currents and increased risk of punch through events.

    摘要： In sophisticated semiconductor devices, different threshold voltage levels for transistors may be set in an early manufacturing stage, i.e., prior to patterning the gate electrode structures, by using multiple diffusion processes and/or gate dielectric materials. In this manner, substantially the same gate layer stacks, i.e., the same electrode materials and the same dielectric cap materials, may be used, thereby providing superior patterning uniformity when applying sophisticated etch strategies.
