  • Two-dimensional micro-mirror array enhancements
    Patent number: 7031045
    Abstract: A micro-mirror strip assembly having a plurality of two-dimensional micro-mirror structures with improved deflection and other characteristics is presented. In the micro-mirror structures, electrodes for electrostatic deflection are disposed on conical or quasi-conical entities that are machined, attached or molded into a substrate. The electrodes are quartered approximately parallel to or offset by 45 degrees from rotational axes to form quadrants. Torsion sensors are provided along the axes of rotation to control deflection of the quadrant deflection electrodes.
    Type: Grant
    Filed: October 28, 2003
    Date of Patent: April 18, 2006
    Inventors: Armand P. Neukermans, Timothy G. Slater, Marc R. Schuman, Jack D. Foster, Sam Calmes, Sateesh S. Bajikar, Arun Malhotra, Jane Ang, Jerry Hurst, John Green

  • Enhanced adhesion for LIGA microfabrication by using a buffer layer
    Patent number: 6682870
    Abstract: The present invention is an improvement on the LIGA microfabrication process wherein a buffer layer is applied to the upper or working surface of a substrate prior to the placement of a resist onto the surface of the substrate. The buffer layer is made from an inert low-Z material (low atomic weight), a material that absorbs secondary X-rays emissions from the substrate that are generated from the substrate upon exposure to a primary X-rays source. Suitable materials for the buffer layer include polyamides and polyimide. The preferred polyimide is synthesized form pyromellitic anhydride and oxydianiline (PMDA-ODA).
