  • Light emitting device substrate with inclined sidewalls
    Patent number: 10096742
    Abstract: A light emitting device having improved light extraction is provided. The light emitting device can be formed by epitaxially growing a light emitting structure on a surface of a substrate. The substrate can be scribed to form a set of angled side surfaces on the substrate. For each angled side surface in the set of angled side surfaces, a surface tangent vector to at least a portion of each angled side surface in the set of angled side surfaces forms an angle between approximately ten and approximately eighty degrees with a negative of a normal vector of the surface of the substrate. The substrate can be cleaned to clean debris from the angled side surfaces.
    Type: Grant
    Filed: December 30, 2015
    Date of Patent: October 9, 2018
    Assignee: Sensor Electronic Technology, Inc.
    Inventors: Maxim S. Shatalov, Jianyu Deng, Alexander Dobrinsky, Xuhong Hu, Remigijus Gaska, Michael Shur
