  • Patent number: 7527544
    Abstract: A method and system are provided using an offset dial gage for alignment and adjustment of a polishing pad that has been attached to a turntable of a chemical mechanical polishing (CMP) device. In a described embodiment, an offset dial gage has a surface that contacts a side of a turntable, while a sensor tip contacts the edge of a polishing pad positioned on the turntable. This provides an assessment of radial displacement of the polishing pad edge at this measurement point relative to the side of the turntable. Based on one or more such measurements, the polishing pad may be found acceptably positioned, may be trimmed, or may be replaced. The method and system reduce or eliminate the occurrence of a defect pattern found to be related to side unloading of semiconductor wafers from a CMP turntable.

  • Publication number: 20070010180
    Abstract: Disclosed herein is an improved carrier design for use in a chemical mechanical polishing process. The carrier employs a retainer ring that is fastened to the side of carrier, as opposed to the front of the carrier, which alleviates undesired uneven wear of the retainer ring surface. Specifically exemplified herein is a carrier comprising a membrane that is secured to the carrier body by a retainer ring that is snap-fitted to the carrier body.

  • Publication number: 20050260936
    Abstract: A conditioner assembly is disclosed for conditioning a polishing pad used in chemical mechanical polishing of planar semiconductor wafer components. One embodiment of the conditioner assembly comprises a plate-type conditioner plate comprising a circular edge, having a first side and a second side, where on the first side is provided one or more diamond-impregnated abrasive elements, each comprising an abrasive surface disposed a distance from said first side comprising diamond particles, and one or more jets oriented to discharge fluid away from said first side. In operation the jets dispense high velocity fluid that hits the surface of the adjacent polishing pad with sufficient force to dislodge diamond particles that have loosened or broken off from the diamond-impregnated abrasive elements, thereby avoiding the embedding of such particles into the polishing pad surface.
