ABSTRACT:
An apparatus for conditioning polishing pads that utilizes an apertured conditioning disk for introducing operation-specific slurries, without the need for additional tooling, platens, and materials handling. The apparatus utilizes a vacuum capability to pull waste material out of the polishing pad and through the apertured conditioning disk to evacuate the apparatus through an outlet port. The apparatus also includes a force adjustment system for providing measurement and control of the force applied by the conditioning disk to the polishing pad.
