Abstract
An apparatus for chemically mechanically polishing includes an arm configured to move a conditioner module. The conditioner module is configured to contact a pad so as to change a degree of roughness of the pad. The pad is configured to contact and polish a semiconductor wafer. The arm has a first end and a second end opposite to the first end. The first end has an electromagnetic module. The conditioner module is detachably magnetically coupled to the arm by means of the electromagnetic module. The second end is coupled to a knob and configured to pivot at the knob. The arm moves the conditioner module through the pivoting of the second end at the knob. The conditioner module is disconnected from the arm when a magnetic polarity at the electromagnetic module is changed.
