    摘要: In advanced semiconductor devices, spacer elements may be formed on the basis of a multi-station deposition technique, wherein a certain degree of variability of the various sub-layers of the spacer materials, such as a different thickness, may be applied in order to enhance etch conditions during the subsequent anisotropic etch process. Consequently, spacer elements of improved shape may result in superior deposition conditions when using a stress-inducing dielectric material. Consequently, yield losses due to contact failures in densely packed device areas, such as static RAM areas, may be reduced.

    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: 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.
