Abstract
A chemical mechanical planarization system includes a chemical mechanical planarization pad that rotates during a chemical mechanical planarization process. A chemical mechanical planarization head places a semiconductor wafer in contact with the chemical mechanical planarization pad during the process. A slurry supply system supplies a slurry onto the pad during the process. A pad conditioner conditions the pad during the process. An impurity removal system removes debris and impurities from the slurry.
