METHODS OF FORMING DIAMOND COMPOSITE CMP PAD CONDITIONER

Methods of forming chemical-mechanical polishing/planarization pad conditioner bodies 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.

IN-SITU CONDITIONER DISK CLEANING DURING CMP

A polishing system includes a platen to hold a polishing pad, a carrier head to hold a substrate against the polishing pad, a conditioner including a conditioner head to hold a conditioner disk against the polishing pad, a motor to move the conditioner head laterally movable relative to the platen, a conditioning disk cleaning station positioned adjacent the platen to clean the conditioning disk, and a controller configured to cause the motor to, during polishing of the substrate, move the conditioner head back and forth between a first position with the conditioner head over the polishing pad and a second position with the conditioner head in the conditioner disk cleaning station.
