Patent ID: 8821750

Claim:
A metal polishing slurry containing abrasive grains, a metal-oxide-dissolving agent, a metal oxidizing agent, a metal anticorrosive agent, an organic solvent, and water, wherein the abrasive grains are colloidal silica and contain 1 to 50% by mass of first abrasive grains having an average secondary particle diameter being in the range of 5 to 39 nm and 50 to 99% by mass of second abrasive grains having an average secondary particle diameter being in the range of 40 to 150 nm, the metal-oxide-dissolving agent is at least one selected from organic acids, organic-acid esters, ammonium salts of organic acids, and inorganic acids, the metal oxidizing agent is at least one selected from hydrogen peroxide, nitric acid, potassium periodate, hypochlorous acid, and ozone water, the metal anticorrosive agent is at least one selected from a compound having a triazole skeleton, a compound having a pyrazole skeleton, a compound having a pyrimidine skeleton, a compound having an imidazole skeleton, a compound having a guanidine skeleton, and a compound having a thiazole skeleton, and a pH is in the range of 2 to 4, and wherein the abrasive grains consist of the colloidal silica.
