  • Patent number: 8210904
    Abstract: A patterned portion of a patterned semiconductor substrate is removed by abrasive mechanical planarization employing an abrasive pad but without employing any slurry. Preferably, water is supplied to enhance the removal rate during the mechanical planarization. The removal rate of material is substantially independent for common materials employed in back-end-of-line (BEOL) semiconductor materials, which enables non-selective removal of the material containing metallization structures. The removal rate of silicon is lower than the removal rate for the BEOL semiconductor materials, enabling a self-stopping planarization process.

  • 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.
