    摘要: 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.
