  • Publication number: 20140035169
    Abstract: A structure and method for fabricating the structure that provides a metal wire having a first height at an upper surface. An insulating material surrounding said metal wire is etched to a second height below said first height of said upper surface. The metal wire from said upper surface, after etching said insulating material, is planarized to remove sufficient material from a lateral edge portion of said metal wire such that a height of said lateral edge portion is equivalent to said second height of said insulating material surrounding said metal wire.

  • Patent number: 8088690
    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.
