David Charles Joy 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).

  • Patterning methods and systems using reflected interference patterns
    Patent number: 6967067
    Abstract: A method for patterning a layer on a substrate can include projecting coherent radiation toward a reflector surface so that the coherent radiation is reflected off the reflector surface to provide a holographic projection of a desired image wherein the reflector surface includes information that corresponds to an inverse of the holographic projection of the desired image. The substrate including the layer can be maintained in the path of the reflected radiation so that the holographic projection is projected onto the layer. Related systems are also discussed.
    Type: Grant
    Filed: March 9, 2004
    Date of Patent: November 22, 2005
    Assignee: University of Tennessee Research Foundation
