Zusammenfassung:An additive composition for a slurry contains a first salt of polymeric acid including a first polymeric acid having a first weight average molecular weight and a first base material, and a second salt of polymeric acid including a second polymeric acid having a second weight average molecular weight and a second base material. A slurry composition is prepared by mixing the additive composition, a polishing particle composition, and water. When implementing a chemical mechanical polishing using the slurry composition, a favorable polishing selectivity is realized.
