    Abstract: The instant invention is a method of polishing a substrate including contacting a substrate having at least one metal layer including copper with a chemical-mechanical polishing composition. The CMP composition includes an abrasive, a surfactant, an oxidizer, an organic acid including polyacrylic acid or polymethacrylic acid, a corrosion inhibitor, and a liquid carrier. A portion of the copper in the metal layer is abraded to polish the substrate. A second CMP composition contacts the abraded substrate, the second acrylate free composition including an abrasive, a surfactant, an oxidizer, and a corrosion inhibitor, and a liquid carrier. Any dendrites that may have formed on the substrate are removed through abrasion.

    Abstract: A structure and a method for forming the same. The structure includes (a) an interlevel dielectric (ILD) layer; (b) a first electrically conductive line and a second electrically conductive line both residing in the ILD layer; (c) a diffusion barrier region residing in the ILD layer. The diffusion barrier region (i) physically isolates, (ii) electrically couples together, and (iii) are in direct physical contact with the first and second electrically conductive lines. The first and second electrically conductive lines each comprises a first electrically conductive material. The diffusion barrier region comprises a second electrically conductive material different fro m the first electrically conduct ive material. The diffusion barrier region is adapted to prevent a diffusion of the first electrically conductive material through the diffusion barrier region.
