Zusammenfassung: | In one embodiment, a polishing composition can comprise abrasive particles including zirconia, an oxidizing agent including hydroxylamine and water. The polishing composition can have a high copper removal rate of at least 3500 Å/min, and a polishing selectivity of copper to silicon dioxide(Cu:SiO2) can be at least 2.5:1. In another embodiment, a combination product can comprise a first polishing composition and a second polishing composition, wherein each of the first polishing composition and the second polishing composition can comprise abrasive particles including zirconia and an oxidizing agent including hydroxylamine, wherein a hydroxylamine weight % ratio of the first polishing composition to the second polishing composition may be at least 5:1. |
