    摘要: The invention provides a method of preparing a chemical-mechanical polishing composition for polishing a substrate with at least a first layer and a second layer. The method comprises providing both a first chemical-mechanical polishing composition comprising an abrasive with a selectivity for a first layer as compared to a second layer and a second chemical-mechanical polishing composition comprising an abrasive with different selectivity for the first layer as compared to the second layer, wherein the second chemical-mechanical polishing composition is stable in the presence of the first chemical-mechanical polishing composition, and mixing the first and second chemical-mechanical polishing compositions in a ratio to achieve a final selectivity for the first layer as compared to the second layer. The invention further provides a method of chemically-mechanically polishing a substrate.
