    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: When forming transistor elements on the basis of sophisticated high-k metal gate structures, the efficiency of a replacement gate approach may be enhanced by more efficiently adjusting the gate height of transistors of different conductivity type when the dielectric cap layers of transistors may have experienced a different process history and may thus require a subsequent adaptation of the final cap layer thickness in one type of the transistors. For this purpose, a hard mask material may be used during a process sequence for forming offset spacer elements in one gate electrode structure while covering another gate electrode structure.

    摘要: A method that includes forming a gate of a semiconductor device on a substrate, and etching sidewall spacers on sides of the gate to provide a proximity value, where the proximity value is defined as a distance between the gate and an edge of a performance-enhancing region. The sidewall spacers are used to define the edge of the region during formation of the region in the substrate. The method also includes pre-cleaning the gate and the substrate in preparation for formation of the region, where the etching and the pre-cleaning are performed in a continuous vacuum.

    摘要: Disclosed herein are various methods of forming metal silicide regions on semiconductor devices. In one example, the method includes forming a sacrificial gate structure above a semiconducting substrate, performing a selective metal silicide formation process to form metal silicide regions in source/drain regions formed in or above the substrate, after forming the metal silicide regions, removing the sacrificial gate structure to define a gate opening and forming a replacement gate structure in the gate opening, the replacement gate structure comprised of at least one metal layer.

    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.
