Corrosion-Resistant CMP Conditioning Tools and Methods for Making and Using Same

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...

Beschreibung
Zusammenfassung:	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.
