Hung-Ta Chang 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).

  • ELECTROMECHANICAL DISPLAY DEVICES AND METHODS OF FABRICATING THE SAME
    Publication number: 20110157010
    Abstract: MEMS devices include materials which are used in LCD or OLED fabrication to facilitate fabrication on the same manufacturing systems. Where possible, the same or similar materials are used for multiple layers in the MEMS device, and use of transparent conductors for partially transparent electrodes can be avoided to minimize the number of materials needed and minimize fabrication costs. Certain layers comprise alloys selected to achieve desired properties. Intermediate treatment of deposited layers during the manufacturing process can be used to provide layers having desired properties.
    Type: Application
    Filed: March 7, 2011
    Publication date: June 30, 2011
    Applicant: QUALCOMM MEMS Technologies, Inc.
    Inventors: Manish Kothari, Hung-Ta Chang, Jan Bos, Surya Prakash Ganti
