Abstract

The present invention provides a method of manufacturing a semiconductor device using a polishing apparatus having a polishing pad conditioning wheel. In one embodiment, the polishing pad conditioning wheel comprises a conditioning head, a setting alloy, an abrasive material, and a corrosion resistant coating. The conditioning head has opposing first and second faces with the first face being coupleable to the polishing apparatus. The setting alloy is coupled to the conditioning head at the second face, and the abrasive material is embedded in the setting alloy, which is substantially covered by the corrosion resistant coating.
