Abstract:
A process for chemical mechanical polishing a substrate containing titanium nitride and titanium is provided comprising: providing a polishing composition, containing, as initial components: water; an oxidizing agent; a linear polyalkylenimine polymer; a colloidal silica abrasive with a positive surface charge; a carboxylic acid; a source of ferric ions; and, optionally pH adjusting agent; wherein the polishing composition has a pH of 1 to 4; providing a chemical mechanical polishing pad, having a polishing surface; creating dynamic contact at an interface between the polishing pad and the substrate; and dispensing the polishing composition onto the polishing surface at or near the interface between the polishing pad and the substrate; wherein at least some of the titanium nitride and at least some of the titanium is polished away with a selectivity between titanium nitride and titanium.

Claim (Index 6):
The method of  claim 1 , wherein the chemical mechanical polishing composition provided, consists of, as initial components:\n the water; the oxidizing agent; the linear polyalkylenimine polymer; the colloidal silica abrasive; the carboxylic acid; the source of ferric ions, wherein the source of ferric ions is ferric nitrate; and, the optional pH adjusting agent.
