    摘要: A detection system and method including a means for performing a test on a semiconductor device and obtaining test data therefrom. The semiconductor device includes an insulating layer, a hard mask layer on a surface of the insulating layer, and a plurality of electrically conductive lines within a trench in the insulating layer. The insulating layer comprises a first dielectric material. The hard mask layer comprises a second dielectric material. The dielectric constant of the second dielectric material exceeds the dielectric constant of the first dielectric material or the second dielectric material comprises an element that is not comprised by the first dielectric material. The test data is a function of a spatial distribution of the hard mask layer on the surface of the insulating layer. The detection system and method includes a means for determining from the test data a measure of the spatial distribution of the hard mask layer on the surface of the insulating layer.

    摘要: 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 and enough 70% wt nitric acid to adjust the pH of the slurry to about 1.2 to 1.4.

    摘要: A substantial reduction in the foreign particulate matter contamination on surfaces, such as the surfaces of semiconductor wafers, is achieved by treating the surfaces with a solution comprising a strong acid and a very small amount of a fluorine-containing compound. A preferred method employs a solution containing sulfuric acid, hydrogen peroxide and a very small amount of hydrofluoric acid, which is effective in reducing foreign particulate matter contamination, without significant etching, of the surface being treated.

    摘要: A solution for forming a polishing slurry, the polishing slurry and related methods are disclosed. The solution for forming a polishing slurry may include 1 H-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.

    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.
