SLURRY COMPOSITION FOR CHEMICAL MECHANICAL POLISHING OF METAL AND POLISHING METHOD USING THE SAME

摘要

Provided is a slurry composition for chemical mechanical polishing (CMP) of a metal. The slurry composition comprises a copolymer whose average molecular weight is from about 600,000 to about 1,300,000 and whose monomers are acrylic acid and acrylamide in a molar ratio of about 1:30 to about 30: 1. The slurry composition exhibits a non-Prestonian behavior to achieve minimized dishing and attain a high degree of planarization.
