    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 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.

    摘要： A method of forming a semiconductor structure comprises providing a semiconductor substrate comprising a first transistor element and a second transistor element. Each of the first transistor element and the second transistor element comprises a gate electrode. A stressed material layer is deposited over the first transistor element and the second transistor element. The stressed material layer is processed to form from the stressed material layer sidewall spacers adjacent the gate electrode of the second transistor element and a hard mask covering the first transistor element. A pair of cavities is formed adjacent the gate electrode of the second transistor element. A pair of stress-creating elements is formed in the cavities and the hard mask is at least partially removed.

    摘要： In sophisticated semiconductor devices, the initial strain component of a globally strained semiconductor layer may be substantially preserved during the formation of shallow trench isolations by using a rigid mask material, which may efficiently avoid or reduce a deformation of the semiconductor islands upon patterning the isolation trenches. Consequently, selected regions with high internal stress levels may be provided, irrespective of the height-to-length aspect ratio, which may limit the application of globally strained semiconductor layers in conventional approaches. Furthermore, in some illustrative embodiments, active regions of substantially relaxed strain state or of inverse strain type may be provided in addition to the highly strained active regions, thereby enabling an efficient process strategy for forming complementary transistors.

    摘要： An efficient strain-inducing mechanism may be implemented in the form of differently stressed material layers that are formed above transistors of different types. The strain-inducing dielectric materials may be formed so as to be in direct contact with the corresponding transistors, thereby enhancing the overall strain transfer efficiency. Moreover, the disclosed manufacturing strategy avoids or at least significantly reduces any interaction of reactive etch atmospheres used to pattern the strain-inducing material layers with metal silicide regions, which may be formed individually for each type of transistor.
