    摘要: When forming sophisticated semiconductor devices including complementary transistors having a reduced gate length, the individual transistor characteristics may be adjusted on the basis of individually provided semiconductor alloys, such as a silicon/germanium alloy for P-channel transistors and a silicon/phosphorous semiconductor alloy forN-channel transistors. To this end, a superior hard mask patterning regime may be applied in order to provide compatibility with sophisticated replacement gate approaches, while avoiding undue process non-uniformities, in particular with respect to the removal of a dielectric cap layer.

    摘要: When forming sophisticated gate electrode structures, such as high-k metal gate electrode structures, an appropriate encapsulation may be achieved, while also undue material loss of a strain-inducing semiconductor material that is provided in one type of transistor may be avoided. To this end, the patterning of the protective spacer structure prior to depositing the strain-inducing semiconductor material may be achieved for each type of transistor on the basis of the same process flow, while, after the deposition of the strain-inducing semiconductor material, an etch stop layer may be provided so as to preserve integrity of the active regions.

    摘要: A strain-inducing semiconductor alloy may be formed on the basis of cavities which may have a non-rectangular shape, which may be maintained even during corresponding high temperature treatments by providing an appropriate protection layer, such as a silicon dioxide material. Consequently, a lateral offset of the strain-inducing semiconductor material may be reduced, while nevertheless providing a sufficient thickness of corresponding offset spacers during the cavity etch process, thereby preserving gate electrode integrity. For instance, P-channel transistors may have a silicon/germanium alloy with a hexagonal shape, thereby significantly enhancing the overall strain transfer efficiency.

    摘要: When forming sophisticated transistors on the basis of a high-k metal gate electrode structure and a strain-inducing semiconductor alloy, a superior wet cleaning process strategy is applied after forming cavities in order to reduce undue modification of sensitive gate materials, such as high-k dielectric materials, metal-containing electrode materials and the like, and modification of a threshold voltage adjusting semiconductor alloy. Thus, the pronounced dependence of the threshold voltage of transistors of different width may be significantly reduced compared to conventional strategies.
