In the apparatus, an upper platform for mounting a conditioning disc thereto and a lower platform for mounting a polishing pad thereto are engaged together under a pre-set pressure and rotated in opposite directions for a pre-set length of time. The apparatus is effective in removing loose particles from the surface of the conditioning disc such that the possibility of any such particles causing scratches on a wafer surface during a subsequently conducted chemical mechanical polishing process is eliminated. The present invention novel apparatus can be used off-line for pre-conditioning a conditioning disc such that valuable machine time of a chemical mechanical polishing apparatus is not wasted.
