    摘要: In a replacement gate approach for forming high-k metal gate electrodes in semiconductor devices, a tapered configuration of the gate openings may be accomplished by using a tensile stressed dielectric material provided laterally adjacent to the gate electrode structure. Consequently, superior deposition conditions may be achieved while the tensile stress component may be efficiently used for the strain engineering in one type of transistor. Furthermore, an additional compressively stressed dielectric material may be applied after providing the replacement gate electrode structures.

    摘要: By forming an isolation structure that extends above the height level defined by the semiconductor material of an active region, respective recesses may be defined in combination with gate electrode structures of the completion of basic transistor structures. These recesses may be subsequently filled with an appropriate contact material, thereby forming large area contacts in a self-aligned manner without requiring deposition and patterning of an interlayer dielectric material. Thereafter, the first metallization layer may be formed, for instance, on the basis of well-established techniques wherein the metal lines may connect directly to respective “large area” contact elements.

    摘要: Air gaps may be provided in a self-aligned manner with sub-lithography resolution between closely spaced metal lines of sophisticated metallization systems of semiconductor devices by recessing the dielectric material in the vicinity of the metal lines and forming respective sidewall spacer elements. Thereafter, the spacer elements may be used as an etch mask so as to define the lateral dimension of a gap on the basis of the corresponding air gaps, which may then be obtained by depositing a further dielectric material.

    摘要: OPC results may be efficiently evaluated on the basis of a test structure containing a plurality of line features with opposing end portions. Thus, for different line parameters, the effect of OPC may be determined for a given critical tip-to-tip distance by determining the leakage behavior of the test assemblies, each having different design parameter values for line width and lateral distance between adjacent lines.

    摘要: By incorporating an etch control material after the formation of a material layer to be patterned, an appropriate material having a highly distinctive radiation wavelength may be used for generating a distinctive endpoint detection signal during an etch process. Advantageously, the material may be incorporated by ion implantation which provides reduced non-uniformity compared to etch non-uniformities, while the implantation process provides the potential for introducing even very “exotic” implantation species. In some embodiments, the substrate-to-substrate uniformity of the patterning of dual damascene structures may be increased.
