Patent number: 7527544Abstract: 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.Type: GrantFiled: January 3, 2008Date of Patent: May 5, 2009Assignee: Agere Systems Inc.Inventors: Jose Omar Rodriguez, Charles A. Storey, Andres B. Garcia, Margareth Seputro, Frank Miceli

Patent number: 6750145Abstract: The present invention, in one embodiment, provides a method for eliminating agglomerate particles in a polishing slurry. In this particular embodiment, the method is directed to reducing agglomeration of slurry particles within a waste slurry passing through a slurry system drain. The method comprises conveying the waste slurry to the drain, wherein the waste slurry may form an agglomerate having an agglomerate particle size. The method further comprises subjecting the waste slurry to energy emanating from an energy source. The energy source thereby transfers energy to the waste slurry to substantially reduce the agglomerate particle size. Substantially reduce means that the agglomerate is size is reduced such that the waste slurry is free to flow through the drain.Type: GrantFiled: November 14, 2001Date of Patent: June 15, 2004Assignee: Agere Systems Inc.Inventors: Annette M. Crevasse, William G. Easter, John A. Maze, Sailesh M. Merchant, Frank Miceli

Patent number: 6615433Abstract: The present invention provides a wafer cleaning apparatus. In an advantageous embodiment, the wafer cleaning apparatus includes cleaning brushes mounted within a brush box and a sensor associated with at least one of the cleaning brushes and configured to detect a degree of wetness of the at least one of the cleaning brushes. In most cases, the cleaning brushes are comprised of an absorbent material, such as polyvinyl alcohol, that becomes more compressible as the cleaning brushes become more wetted with a solution. Thus, a degree of compressibility can be related to a degree of wetness of a cleaning brush, which provides data that allows an operator to determine when the cleaning brushes are wet enough to send a wafer through the cleaning apparatus without incurring unnecessary damage.Type: GrantFiled: March 29, 2001Date of Patent: September 9, 2003Assignee: Agere Systems Inc.Inventors: Annette M. Crevasse, William G. Easter, John A. Maze, Frank Miceli
