  • Patent number: 8129275
    Abstract: In order to provide an anticorrosive technique for metal wirings formed by a chemical mechanical polishing (CMP) method, a process for manufacturing a semiconductor integrated circuit device according to the invention comprises the steps of: forming a metal layer of Cu (or a Cu alloy containing Cu as a main component) over the major face of a wafer and then planarizing the metal layer by a chemical mechanical polishing (CMP) method to form metal wirings; anticorroding the planarized major face of the wafer to form a hydrophobic protective film over the surfaces of the metal wirings; immersing the anticorroded major face of the wafer or keeping the same in a wet state so that it may not become dry; and post-cleaning the major face, kept in the wet state, of the wafer.

  • Patent number: 7026245
    Abstract: In order to polish an insulating film, a cerium oxide polishing agent (ceria slurry) is used. The ceria slurry is composed of cerium oxide powder containing Na, Ca, Fe, and Cr concentration of which is less than 10 ppm. Fragile inorganic and organic insulating films formed at relatively low temperatures can be polished without degrading the characteristics of the semiconductor element due to Na diffusion.

  • Patent number: 6855035
    Abstract: The apparatus and method for producing a substrate having a substrate surface by polishing the substrate surface, which includes a metallic wire. A polishing liquid is supplied a clearance between the substrate surface and the surface of a polishing pad. The polishing liquid includes an acid which dissolves the oxidized part of the substrate surface and is substantially free of solid abrasive powder. A relative movement is generated between the substrate surface and the polishing pad surface while the substrate surface is pressed against the polishing pad surface while the polishing liquid is supplied so that the dissolved oxidized part of the substrate surface can be removed from the substrate.
