摘要: A method and apparatus for conditioning a polishing pad in a CMP system is provided. In one embodiment, a method for conditioning a polishing pad includes applying a down force to the conditioning disk that urges the conditioning disk against the polishing pad, measuring a torque required to sweep the conditioning disk across the polishing pad, determining a change in down force by comparing the measured torque to a model force profile (MFP), and adjusting the down force that the conditioning disk applies against the polishing pad in response to the determined change.
