  • Micro corner cube array, method of making the micro corner cube array and reflective type display device
    Patent number: 7518676
    Abstract: A method of making a micro corner cube array includes the steps of: preparing a substrate, at least a surface portion of which consists of cubic single crystals and which has a surface that is substantially parallel to {111} planes of the crystals; and etching the surface of the substrate anisotropically, thereby forming a plurality of unit elements for the micro corner cube array on the surface of the substrate. Each of these unit elements is made up of a number of crystal planes that have been formed at a lower etch rate than the {111} planes of the crystals.
    Type: Grant
    Filed: March 8, 2006
    Date of Patent: April 14, 2009
    Assignee: Sharp Kabushiki Kaisha
    Inventors: Kiyoshi Minoura, Shun Ueki, Yasuhisa Itoh, Ichiroh Ihara, Yutaka Sawayama, Kohji Taniguchi
