    摘要: A borderless contact structure or partially borderless contact structure and methods of manufacture are disclosed. The method includes forming a gate structure and a space within the gate structure, defined by spacers. The method further includes blanket depositing a sealing material in the space, over the gate structure and on a semiconductor material. The method further includes removing the sealing material from over the gate structure and on the semiconductor material, leaving the sealing material within the space. The method further includes forming an interlevel dielectric material over the gate structure. The method further includes patterning the interlevel dielectric material to form an opening exposing the semiconductor material and a portion of the gate structure. The method further includes forming a contact in the opening formed in the interlevel dielectric material.

    摘要: An interconnect structure having enhanced electromigration resistance is provided in which a lower portion of a via opening includes a multi-layered liner. The multi-layered liner includes, from a patterned surface of a dielectric material outwards, a diffusion barrier, a multi-material layer and a metal-containing hard mask. The multi-material layer includes a first material layer comprised of residue from an underlying dielectric capping layer, and a second material layer comprised of residue from an underlying metallic capping layer. The present invention also provides a method of fabricating such an interconnect structure which includes the multi-layered liner within a lower portion of a via opening formed within a dielectric material.

    摘要: A first low dielectric constant (low-k) dielectric material layer is lithographically patterned to form a recessed region having expose substantially vertical sidewalls, which are subsequently damaged to de-carbonize a surface portion at the sidewalls having a sublithographic width. A second low-k dielectric material layer is deposited to fill the recessed region and planarized to exposed top surfaces of the damaged low-k dielectric material portion. The damaged low-k dielectric material portion is removed selective to the first and second low-k dielectric material layers to form a trench with a sublithographic width. A portion of the pattern of the sublithographic-width trench is transferred into a metallic layer and optionally to an underlying dielectric masking material layer to define a trench with a sublithographic width, which can be employed as a template to confine the widths of via holes and line trenches to be subsequently formed in an interconnect-level dielectric material layer.

    摘要: A metal layer is deposited on a planar surface on which top surfaces of underlying metal vias are exposed. The metal layer is patterned to form at least one metal block, which has a horizontal cross-sectional area of a metal line to be formed and at least one overlying metal via to be formed. Each upper portion of underlying metal vias is recessed outside of the area of a metal block located directly above. The upper portion of the at least one metal block is lithographically patterned to form an integrated line and via structure including a metal line having a substantially constant width and at least one overlying metal via having the same substantially constant width and borderlessly aligned to the metal line. An overlying-level dielectric material layer is deposited and planarized so that top surface(s) of the at least one overlying metal via is/are exposed.
