    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: Disclosed are embodiments of a method of removing patterned circuit structures from the surface of a semiconductor wafer. The method embodiments comprise blasting the surface of the semiconductor wafer with particles so as to remove substantially all of the patterned circuit structures. The blasting process is followed by one or more grinding, polishing and/or cleaning processes to remove any remaining circuit structures, to remove any lattice damage and/or to achieve a desired smoothness across the surface of the semiconductor wafer.

    摘要: There is provided a method for making a wafer including the steps of providing a substrate having a first surface, an opposite second surface, and at least one side edge defining a thickness of the substrate, the at least one side edge having a first peripheral region and a second peripheral region adjacent to the first peripheral region. The method includes applying a fluid to the first surface and the first peripheral region of the at least one side edge and removing the opposite second surface and the second peripheral region of the at least one side edge to form a third surface. A semiconductor chip made from the method for making the wafer is also provided.
