摘要: A chemical-mechanical polishing composition includes colloidal silica abrasive particles having a chemical compound incorporated therein. The chemical compound may include a nitrogen-containing compound such as an aminosilane or a phosphorus-containing compound. Methods for employing such compositions include applying the composition to a semiconductor substrate to remove at least a portion of at least one of a copper, a copper barrier, and a dielectric layer.
