Patents by Inventor Richard Dale Coyne

Richard Dale Coyne 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).

  • Acoustic wave device and manufacturing method
    Patent number: 5771556
    Abstract: A method for making an acoustic wave device. The method has steps of providing a substrate suitable for acoustic wave devices and processing the substrate to provide a patterned metallization thereon. The patterned metallization includes an acoustic wave filter pattern. The method also has steps of measuring a sheet resistance associated with the acoustic wave filter pattern, determining a resistance of a test pattern associated with the acoustic wave filter pattern to provide a measured resistance and computing an estimated average linewidth for the acoustic wave filter pattern from the measured resistance and the sheet resistance.
    Type: Grant
    Filed: November 7, 1995
    Date of Patent: June 30, 1998
    Assignee: Motorola Inc.
    Inventors: Donald Eugene Allen, Steven Ray Stringer, Richard Dale Coyne
