Abstract:
Provided are a slurry composition for CMP and a polishing method using the same, in which polishing can be performed by freely adjusting the selectivity ratio of a silicon oxide film, a silicon nitride and a polysilicon film through control of the amounts of additive and solvent, and thus the slurry composition can be efficiently applied to the process of manufacturing a semiconductor, requiring selective removal of a silicon nitride film and a polysilicon film relative to a silicon oxide film.

Claim (Index 7):
The slurry composition for CMP of  claim 1 , wherein the slurry composition for CMP simultaneously polishes films to be polished, including at least two selected from among the silicon oxide film, the silicon nitride film and the polysilicon film.
