Diamond Composite CMP Pad Conditioner
A chemical-mechanical polishing/planarization pad conditioner body made from diamond-reinforced reaction bonded silicon carbide, with diamond particles protruding or “standing proud” of the rest of the surface, and uniformly distributed on the cutting surface. In one embodiment, the diamond particles are approximately uniformly distributed throughout the composite, but in other embodiments they are preferentially located at and near the conditioning surface. The tops of the diamond particles can be engineered to be at a constant elevation (i.e., the conditioner body can be engineered to be very flat). Exemplary shapes of the body may be disc or toroidal. The diamond particles can be made to protrude from the conditioning surface by preferentially eroding the Si/SiC matrix. The eroding may be accomplished by electrical discharge machining or by lapping/polishing with abrasive.
POLISHING PAD-MEASURING APPARATUS AND CHEMICAL MECHANICAL POLISHING FACILITY USING THE SAME
Example embodiments of the inventive concepts provide a polishing pad-measuring apparatus and a chemical mechanical polishing facility using the same. The polishing pad-measuring apparatus includes a foreign material-removing part for removing a foreign material disposed in grooves extending from one surface of a polishing pad toward another surface, opposite to the one surface, of the polishing pad, and a distance measuring part for measuring depths of the grooves from which the foreign material is removed.

Advanced Polishing System
A method for polishing a polishing pad includes detecting, by a first sensor, a presence of a defect formed on a groove of a polishing pad; removing, by a polishing disc, the defect from the groove of the polishing pad; after removing the defect, measuring, by a second sensor, a remaining depth of the groove; and based on the measured remaining depth of the groove, applying, through the polishing disc, a polishing condition on the groove.
