Abstract:
The invention provides a method of chemically-mechanically polishing a substrate comprising providing a substrate comprising a tungsten layer on a surface of the substrate and a silicon oxide layer on a surface of the substrate, providing a chemical-mechanical polishing composition comprising a tungsten layer and a silicon oxide layer using a chemical-mechanical polishing composition comprising a) surface-modified colloidal silica particles, comprising a negatively-charged group on the surface of the particles, wherein the surface-modified colloidal silica particles have a negative charge, a particle size of about 90 nm to about 350 nm, and a zeta potential of about −20 mV to about −70 mV at a pH of about 2, b) an iron compound, c) a stabilizing agent, and d) an aqueous carrier, and contacting the substrate with a polishing pad and the chemical mechanical polishing composition to polish the substrate.

Claim (Index 11):
The method of  claim 1 , wherein the stabilizing agent comprises phosphoric acid, o-phosphorylethanolamine, alendronic acid, acetic acid, phthalic acid, citric acid, adipic acid, oxalic acid, malonic acid, aspartic acid, succinic acid, glutaric acid, pimelic acid, suberic acid, azelaic acid, sebacic acid, maleic acid, glutaconic acid, muconic acid, ethylenediaminetetraacetic acid, propylenediaminetetraacetic acid, or combinations thereof.
