| 摘要 |
The invention provides a chemical-mechanical polishing system for polishing a substrate comprising (a) a polishing component selected from an abrasive, a polishing pad, or both an abrasive and a polishing pad, (b) an aqueous carrier, and (c) the halogen adduct resulting from the reaction of (1) an oxidizing agent selected from the group consisting of iodine, bromine, and a combination thereof, and (2) a carbon acid having a pKa of 3 to 14, wherein the halogen adduct is present in a concentration of 0.001 mM or more in the aqueous carrier. The invention also provides a method of polishing a substrate comprising (i) providing the aforementioned chemical-mechanical polishing system, (ii) contacting the substrate with the polishing system, and (iii) abrading at least a portion of the surface of the substrate with the polishing system to polish the substrate. |
