A system and method for conditioning a polishing pad in a chemical-mechanical polishing process for polishing a semiconductor device. In one aspect, a vibrating conditioning device 20 removes slurry build-up, such a slurry glaze and slurry impregnation, on the polishing pad 10 surface to enhance the polishing pad effectiveness. The vibrating conditioning device 20 includes a vibrating mechanism 30 coupled to a pad conditioning device, such as a conventional pad conditioning disk, to vibrate the pad conditioning device 20 during the conditioning operation. In another aspect, a high pressure spray device 12 removes particles from the polishing pad 10 surface to reduce damage to a semiconductor device during chemical-mechanical polishing. The high pressure spray device 12 includes a tube 22 formed to include a plurality of delivery holes 32 through which a pressurized substance is delivered onto the polishing pad 10 surface.
