摘要:
An abrasive tool for conditioning CMP pads includes abrasive grains coupled to a substrate through a metal bond and a coating, e.g., a fluorine-doped nanocomposite coating. The abrasive grains can be arranged in a self-avoiding random distribution. In one implementation, an abrasive tool includes a coated plate and a coated abrasive article that has two abrading surfaces. Other implementations related to a process for producing an abrasive tool that includes a coating at one or more of its surfaces. Also described are methods for dressing a CMP pad.

An abrasive article including a bonded abrasive body having a bond material made of a vitrified material, abrasive particles comprising a first type of superabrasive material contained in the bond material, a porosity of at least about 50 vol % of the total volume of the bonded abrasive body, and a ΔCTE of not greater than about 5.5 ppm/° C., wherein ΔCTE is defined as a difference between a CTE of the bond material and a CTE of the abrasive particles.
