Patents by Inventor Deoram Persaud

Deoram Persaud has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7556972
    Abstract: Processes and apparatuses are disclosed for detecting and characterizing SiCOH-based dielectric materials during integrated circuit fabrication. The processes generally include chromatographically analyzing a fluid stream generated during a process employed for device fabrication, e.g., during a wet strip, a chemical mechanical planarization process and the like.
    Type: Grant
    Filed: January 25, 2007
    Date of Patent: July 7, 2009
    Assignee: International Business Machines Corporation
    Inventors: Manoj Balachandran, James A. Hagan, Ben Kim, Deoram Persaud, Adam D. Ticknor, Wei-tsu Tseng
  • Patent number: 7510463
    Abstract: The present invention is an apparatus and method for extending the life of abrasive disks used in the conditioning of polishing pads used in chemical mechanical planarization (CMP) of polishing pads used to polish and/or planarize the surfaces of semiconductor wafers during the production of integrated circuits. The invention consists of the a disk comprising a plurality of abrasive segments, each of which is fixed in tangential and radial relationship to one another about the common axis of rotation of the conditioning disk. Means are provided for movement of the abrasive segments, individually or in sets, into or out of the plane of the active abrasive surface of the conditioning disk according to the present invention.

  • Publication number: 20070190788
    Abstract: Reduction of a wafer removing force on a chemical mechanical planarization (CMP) tool that includes planarizing a wafer on a platen at a wafer/platen interface; applying carbonated water to the wafer/platen interface so as to reduce the removing force; and removing the wafer from the platen.
