Zusammenfassung:An auto slurry deliver fine-tune system and a method using the system is discloses. A slurry flow system varies the flow rate of the slurry in a CMP system and the distance between the slurry injector and the polish head of the CMP system. A current detect system detects the current driving the turn-table of the CMP system. Moreover, a judgement system determines whether the current is minimum in order to determine that the flow rate and the distance are optima.
