<p>A polishing fluid for polishing a metal includes, submicron particles, water, and a nonoxidizing reagent for removal of the metal, the nonoxidizing reagent being a hard base anion species of a Lewis base having a chemical bonding affinity for the metal to deter formation of a passivation oxide on the metal, which hard base anion is present in a concentration that maximizes removal of the metal in the absence of the passivation oxide.</p> |
