Abrasive-free chemical mechanical polishing compositions and methods relating thereto

An aqueous abrasive-free composition is useful for chemical mechanical polishing of a patterned semiconductor wafer containing a nonferrous metal. The composition comprises an oxidizer, an inhibitor for the nonferrous metal, 0 to 15 weight percent water soluble modified cellulose, 0 to 15 weight per...

description	An aqueous abrasive-free composition is useful for chemical mechanical polishing of a patterned semiconductor wafer containing a nonferrous metal. The composition comprises an oxidizer, an inhibitor for the nonferrous metal, 0 to 15 weight percent water soluble modified cellulose, 0 to 15 weight percent phosphorus compound, 0.005 to 5 weight percent of an amphiphilic polymer, the amphiphilic polymer having an ionic hydrophilic portion with a carbon number of 2 to 250 and water.
