    摘要: Polishing pads used in CMP machines are consumable components that are typically replaced after a specific number of wafers have been processed. The life of a polishing pad is optimized by controlling the rate of material removal from the polishing pad by the conditioning disk. The conditioning disk removes enough material so the polishing surface can properly process the wafers but does not remove any excess material. Preventing excess material removal extends the life of the polishing pad. During CMP processing, the controller receives data concerning the torque applied to the conditioning disk and the torque applied to the arm to sweep the conditioning disk across the polishing pad. Based upon the detected operating conditions, the system can predict the rate of material removal and adjust the forces applied to the conditioning disk so that the life of the polishing pad is optimized.

    摘要: A load cup apparatus for transferring a substrate in a processing system includes a pedestal assembly having a substrate support, an actuator, and a controller. The actuator is configured to move the pedestal assembly into a loading position in contact with a retaining ring of a carrier head and to generate a retaining ring thickness signal based on a distance travelled by the pedestal assembly. The controller is configured to receive the retaining ring thickness signal from the actuator.

    摘要: A chemical mechanical polishing apparatus includes a metrology system that detects the thickness of the polishing pad as semiconductor wafers are processed and the thickness of the polishing pad is reduced. The chemical mechanical polishing apparatus includes a controller that adjusts the rate of material removal of a conditioning disk when areas of the polishing surface are detected that are higher or lower than the adjacent areas of the polishing pad.
