  • Publication number: 20140349480
    Abstract: Embodiments of the invention provide processes to selectively form a cobalt layer on a copper surface over exposed dielectric surfaces. Embodiments described herein control selectivity of deposition by preventing damage to the dielectric surface, repairing damage to the dielectric surface, such as damage which can occur during the cobalt deposition process, and controlling deposition parameters for the cobalt layer.

  • Publication number: 20140273438
    Abstract: Embodiments of the present invention provide processes to selectively form a metal layer on a conductive surface, followed by flowing a silicon based compound over the metal layer to form a metal silicide layer. In one embodiment, a substrate having a conductive surface and a dielectric surface is provided. A metal layer is then deposited on the conductive surface. A metal silicide layer is formed as a result of flowing a silicon based compound over the metal layer. A dielectric is formed over the metal silicide layer.

  • Publication number: 20140273516
    Abstract: Methods for the repair of damaged low k films are provided. In one embodiment, the method comprises providing a substrate having a low k dielectric film deposited thereon, and exposing a surface of the low k dielectric film to an activated carbon-containing precursor gas to form a conformal carbon-containing film on the surface of the low k dielectric film, wherein the carbon-containing precursor gas has at least one or more Si—N—Si linkages in the molecular structure.

  • Patent number: 8758638
    Abstract: A method for the removal of copper oxide from a copper and dielectric containing structure of a semiconductor chip is provided. The copper and dielectric containing structure may be planarized by chemical mechanical planarization (CMP) and treated by the method to remove copper oxide and CMP residues. Annealing in a hydrogen (H2) gas and ultraviolet (UV) environment removes copper oxide, and a pulsed ammonia plasma removes CMP residues.

  • Publication number: 20120276301
    Abstract: Embodiments described herein provide a method of processing a substrate. The method includes depositing an interface adhesion layer between a conductive material and a dielectric material such that the interface adhesion layer provides increased adhesion between the conductive material and the dielectric material. In one embodiment a method for processing a substrate is provided. The method comprises depositing an interface adhesion layer on a substrate comprising a conductive material, exposing the interface adhesion layer to a nitrogen containing plasma, and depositing a dielectric layer on the interface adhesion layer after exposing the interface adhesion layer to the nitrogen containing plasma.
