Patent ID: 8840798

Claim:
A slurry composition for chemical mechanical polishing, comprising: 0.1% to 20% by weight of an aminosilane-surface treated polishing agent; 0.001% to 5% by weight of any one additive selected from the group consisting of amino acids, amino acid derivatives, salts thereof, and combinations thereof; 0.0001% to 0.5% by weight of a corrosion inhibitor; and 0.01% to 5% by weight of an oxidizing agent; with the balance being a solvent wherein the slurry composition for chemical mechanical polishing has a pH value of 3 to 3.9, a polishing selection ratio for silicon oxide film to silicon nitride film of 7 to 50, and a polishing rate for PETEOS of 1458 Å/min or greater.
