Conditioning wheel for conditioning a semiconductor wafer polishing pad and method of manufacture thereof

摘要

The present invention provides an improved conditioning wheel for conditioning polishing pads used to polish semiconductor wafers. In one embodiment, the conditioning wheel includes a planar body having a metal surface located thereon. The metal surface has abrasive particles embedded therein and a retainer coating deposited over the metal surface and the abrasive particles. The retainer coating inhibits the abrasive particles from dislodging during a conditioning process.
