  • Patent number: 8636917
    Abstract: A solution for forming a polishing slurry, the polishing slurry and related methods are disclosed. The solution for forming a polishing slurry may include 1H-benzotriazole (BTA) dissolved in an ionic surfactant such as a sodium alkyl sulfate solution, and perhaps a polyacrylic acid (PAA) solution. The solution can be filtered and used in a polishing slurry. This approach to solubilizing BTA results in a high BTA concentration in a polishing slurry without addition of foreign components to the slurry or increased safety hazard. In addition, the solution is easier to ship because it is very stable (e.g., can be frozen and thawed) and has less volume compared to conventional approaches. Further, the polishing slurry performance is vastly improved due to the removal of particles that can cause scratching.

  • 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.

  • Patent number: 6355565
    Abstract: A ferric nitrate-alumina based slurry useful for Chemical-Mechanical-Polishing of tungsten metallurgy and silica based oxides on semiconductor substrates in which the suspension and stability of abrasive material in the slurry is essentially stable. The slurry formulation is balanced to provide low residue of foreign material after polishing and due to its reduced ferric nitrate concentration will be less corrosive than prior art slurries. The recipe for the slurry includes of a 30% wt silica suspension, about 800 ml of 40% by wt ferric nonahydrate, liters and enough 70% wt nitric acid to adjust the pH of the slurry to about 1.2 to 1.4.
