  • Article with a metal layer on a substrate
    Patent number: 7709959
    Abstract: An article includes a substrate and a metal layer adhered to a surface of the substrate so as to form an interface. The interface comprises an atomic concentration of carbon that is about 10% or less and of oxygen that is about 10% or less as determined by x-ray photoelectron spectroscopy.

  • Adhesion of a metal layer to a substrate by utilizing an organic acid material
    Patent number: 7527826
    Abstract: Methods and resulting structures are described in which a metal layer is adhered to a surface of a substrate. The methods involve applying a sacrificial acidic organic layer to the surface of the substrate prior to depositing the metal layer onto the substrate. During deposition of the metal layer, the sacrificial acidic organic layer is substantially consumed, thereby leaving behind a metal/substrate interface that has excellent adhesion properties.
