Abstract:
A process for chemical mechanical polishing a substrate containing tungsten and titanium is provided comprising: providing the substrate; providing a polishing composition, containing, as initial components: water; an oxidizing agent; an allylamine additive; a carboxylic acid; a source of iron ions; a colloidal silica abrasive with a positive surface charge; and, optionally pH adjusting agent; 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 the tungsten (W) is selectively polished away from the substrate relative to the titanium (Ti).

Claim (Index 9):
The method of  claim 8 , wherein the titanium (Ti) removal rate is \u226450 \u212b/min and wherein the tungsten (W) removal rate is \u226535 times higher than the titanium (Ti) removal rate.
