Metal polishing slurry having a static etch inhibitor and method of formulation

摘要

A metal polishing slurry having a static etch inhibitor and method for polishing a substrate while inhibiting static etching during the polishing of a substrate. The slurry composition includes an iodate-free halogenated inhibiting compound added to a generic slurry to form a resultant slurry. The substrate is polished using the resultant slurry, which inhibits the static etching of the substrate being polished. Also provided is a metal polishing slurry for inhibiting static etch comprising an oxidizer, a complexing agent, and an iodate-free halogenated inhibiting compound.
