    摘要: By forming a metal line extending through the entire interlayer dielectric material in resistance sensitive metallization layers, enhanced uniformity of these metallization layers may be obtained. The patterning of respective via openings may be accomplished on the basis of a recess formed in a cap layer, which additionally acts as an efficient etch stop layer during the patterning of the trenches, which extend through the entire interlayer dielectric material. Consequently, for a given design width of metal lines in resistance sensitive metallization layers, a maximum cross-sectional area may be obtained for the metal line with a high degree of process uniformity irrespective of a variation of the via density.

    摘要: By removing excess material of an interlayer dielectric material deposited by SACVD, the gap filling capabilities of this deposition technique may be exploited, while, on the other hand, negative effects of this material may be reduced. In other aspects, a buffer material, such as silicon dioxide, may be formed prior to depositing the interlayer dielectric material on the basis of SACVD, thereby creating enhanced uniformity during the deposition process when depositing the interlayer dielectric material on dielectric layers having different high intrinsic stress levels. Consequently, the reliability of the interlayer dielectric material may be enhanced while nevertheless maintaining the advantages provided by an SACVD deposition.

    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.
