  • Publication number: 20240009801
    Abstract: A method of conditioning a polishing pad includes conditioning the polishing pad using a conditioner. The method includes detecting a roughness of the polishing pad following the conditioning. The method further includes tracking a number of iterations of the conditioning of the polishing pad. The method further includes outputting a signal for replacing the polishing pad in response to the number of iterations reaching an iteration limit. The method further includes repeating the conditioning in response to the detected roughness of the polishing pad being outside of a threshold roughness range and the number of iterations failing to reach the iteration limit.
