James L. Hardy, Jr. 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: 8210904
    Abstract: A patterned portion of a patterned semiconductor substrate is removed by abrasive mechanical planarization employing an abrasive pad but without employing any slurry. Preferably, water is supplied to enhance the removal rate during the mechanical planarization. The removal rate of material is substantially independent for common materials employed in back-end-of-line (BEOL) semiconductor materials, which enables non-selective removal of the material containing metallization structures. The removal rate of silicon is lower than the removal rate for the BEOL semiconductor materials, enabling a self-stopping planarization process.
    Type: Grant
    Filed: April 29, 2008
    Date of Patent: July 3, 2012
    Assignee: International Business Machines Corporation

  • Patent number: 8034718
    Abstract: Disclosed are embodiments of a method of removing patterned circuit structures from the surface of a semiconductor wafer. The method embodiments comprise blasting the surface of the semiconductor wafer with particles so as to remove substantially all of the patterned circuit structures. The blasting process is followed by one or more grinding, polishing and/or cleaning processes to remove any remaining circuit structures, to remove any lattice damage and/or to achieve a desired smoothness across the surface of the semiconductor wafer.
