  • Patent number: 10607853
    Abstract: The present invention relates to a CMP slurry composition for polishing a copper line, the CMP slurry composition comprising a colloidal silica, an oxidizing agent, a complexing agent, a corrosion inhibitor, a pH regulator, and ultrapure water. The colloidal silica has a specific surface area (BET) of 72.9 to 88.5 m2/g, and 0.1 to 2 wt % of the colloidal silica is included in the CMP slurry composition. The CMP slurry composition has an excellent copper line polishing rate, has a low number of defects and minimizes scratches after polishing, and can minimize dishing.
