    摘要: A method of restoring the dielectric constant, loss and leakage of an exposed surface of a low k dielectric material caused during dry etching of the low k dielectric material prior to the removal of the damaged layer by wet etch chemistries is provided. Once restored, the surface of the dielectric material will no longer be susceptible to removal by the highly anisotropic wet etching process. However, the wet etch will still pose an advantage as it can remove any etch/ash residues at the bottom of a feature formed into the low k dielectric material.

    摘要: An interconnect structure having partially self aligned vias with an interlayer dielectric layer on a substrate, containing at least two conducting metal lines that traverse parallel to the substrate and at least two conducting metal vias that are orthogonal to the substrate. A method of producing the self aligned vias by depositing an interlayer dielectric layer onto a substrate, depositing at least one hardmask onto the interlayer dielectric layer, lithographically forming a via pattern with elongated via features and lithographically forming a line pattern in either order, then either transferring the line patterns first into the interlayer dielectric layer forming line features or transferring the via pattern first into the interlayer dielectric layer as long as the patterns overlap to forming self aligned via features, depositing conducting metals and filling regions corresponding to the line and via features, and planarizing and removing excess metal from the line and via features.

    摘要: A method for forming a self aligned pattern on an existing pattern on a substrate comprising applying a coating of the masking material to the substrate; and allowing at least a portion of the masking material to preferentially attach to portions of the existing pattern. The pattern is comprised of a first set of regions of the substrate having a first atomic composition and a second set of regions of the substrate having a second atomic composition different from the first composition. The first set of regions may include one or more metal elements and the second set of regions may include a dielectric. The masking material may comprise a polymer containing a reactive grafting site that selectively binds to the portions of the pattern. The masking material may include a polymer that binds to the portions of the pattern to provide a layer of functional groups suitable for polymerization initiation, a reactive molecule having functional groups suitable for polymerization propagation, or a reactive molecule, wherein reaction of the reactive molecule with the portion of the pattern generates a layer having reactive groups, which participate in step growth polymerization. Structures in accordance with the method. Compositions for practicing the method.
