A semiconductor wafer processing system, more specifically, a chemical mechanical planarization system including a polishing media reconditioning system. In one embodiment, the polishing media reconditioning system comprises at least a first and second conditioning roller that contact a working surface of a polishing media while rotating in opposite directions. Other embodiments include conditioning plates disposed on a carrier that includes the polishing head, a conditioning roller or disk that traverses the surface of the polishing media and a conditioning disk that conditions the polishing media while retained in the polishing head. Alternatively, the polishing media may be conditioned utilizing the devices embodied above remotely from the processing system.
