    摘要： Improved slurry compositions comprising a mixture of a first type of particles and a second type of abrasive particles dispersed within an aqueous medium, and abrasive slurry compositions for use chemical mechanical planarization (CMP) processes, particularly abrasive slurry compositions for polishing of sapphire. These abrasive slurry compositions comprise a mixture of a first type of abrasive particles having a hardness that is harder than the surface being polished and a second type of abrasive particles have a hardness that is softer than the surface being polished, particularly mixtures of silicon carbide abrasive particles and silica abrasive particles, dispersed within an aqueous medium.

    摘要： The invention provides a method of polishing a substrate comprising a metal layer comprising copper. The method comprises the steps of (i) providing a chemical-mechanical polishing system comprising a liquid carrier, a polishing pad, an abrasive, and a negatively-charged polymer or copolymer, (ii) contacting the substrate with the poloshing system, and (iii) abrading at least a portion of the substrate to polish the metal layer of the substrate. The negatively-charged polymer or copolymer comprises one or more monomers selected from sulfonic acids, sulfonates, sulfates, phosphonic acids, phosphonates, and phosphates, has a molecular weight of about 20,000 g/mol or more, and coats at least a portion of the abrasive such that the abrasive has a zeta potential value that is lowered upon interaction of the negatively-charged polymer or copolymer with the abrasive.

    摘要： The invention provides a method of polishing a substrate comprising a noble metal comprising (i) contacting the substrate with a CMP system and (ii) abrading at least a portion of the substrate to polish the substrate. The CMP systems each comprise an abrasive and/or polishing pad, a liquid carrier, and optionally one or more polishing additives. In a first embodiment, the polishing additives are selected from the group consisting of diketones, diketonates, heterocyclic nitrogen-containing compounds, heterocyclic oxygen-containing compounds, heterocyclic phosphorus-containing compounds, urea compounds, nitrogen-containing compounds that can be zwitterionic compounds, salts thereof, and combinations thereof. In a second embodiment, the polishing additive is a metal compound with two or more oxidation states and is used in conjunction with a peroxy-type oxidizer. In a third embodiment, the CMP system comprises &agr;-alumina and fumed alumina, wherein the weight ratio of &agr;-alumina to fumed alumina is about 0.6:1 to about 9:1.
