摘要:
A chemical mechanical polishing composition and slurry comprising a composition capable of etching tungsten and at least one inhibitor of tungsten etching and methods for using the composition and slurry to polish tungsten containing substrates.
摘要:
A chemical mechanical polishing precursor composition comprising at least one catalyst having multiple oxidation states, and at least one stabilizer, the composition being useful when admixed with an oxidizing agent prior to use to remove metal layers from a substrate. Also disclosed is a chemical mechanical polishing composition comprising an oxidizing agent and at least one catalyst having multiple oxidation sites, the composition being useful when combined with an abrasive or an abrasive pad to remove metal layers from a substrate.
