ABSTRACT:
A chemical-mechanical-polishing (CMP) process in which a metal interconnect material (47) is polished to form a metal plug (48) includes the application of titanium to the surface of a polishing pad (14) of a polishing apparatus (10). Titanium metal is applied to the surface of the polishing pad (14) by either abrasively applying titanium by use of a titanium block (32) attached to a rotating disk (26), or by a titanium body (23, 25) integrated with a carrier ring (23). Alternatively, titanium can be applied by impregnating a felt layer (52) with titanium particles (56), or by adding titanium directly to the polishing slurry (50).
