  • Light emitting devices and components having improved chemical resistance and related methods
    Patent number: 11563156
    Abstract: Light emitting devices and components having excellent chemical resistance and related methods are disclosed. In one embodiment, a component of a light emitting device can include a silver (Ag) portion, which can be silver on a substrate, and a protective layer disposed over the Ag portion. The protective layer can at least partially include an inorganic material for increasing the chemical resistance of the Ag portion.
    Type: Grant
    Filed: January 31, 2019
    Date of Patent: January 24, 2023
    Assignee: CreeLED, Inc.
    Inventors: Shaow B. Lin, James Sievert, Jesse Colin Reiherzer, Barry Rayfield, Christopher P. Hussell

  • LIGHT EMITTING DIODES INCLUDING LIGHT EMITTING SURFACE BARRIER LAYERS, AND METHODS OF FABRICATING SAME
    Publication number: 20140175473
    Abstract: A light emitting device includes a Light Emitting Diode (LED) having a light emitting surface, a silicon nitride layer on the light emitting surface and a sealed environment surrounding the light emitting surface. The silicon nitride layer may be directly on and cover the light emitting surface. The silicon nitride layer may completely cover the light emitting surface. The silicon nitride layer may provide a substance blocking layer such as a moisture blocking layer and/or a carbon blocking layer that can prevent moisture and/or carbon, such as Volatile Organic Compounds (VOCs) that contain carbon, from reaching the light emitting surface.

  • Methods for reducing contamination of semiconductor devices and materials during wafer processing
    Patent number: 7531431
    Abstract: Methods of processing a semiconductor structure including a metal layer in the presence of organic material include flowing an aqueous mixture including an oxidizing agent over the semiconductor structure during processing of the semiconductor structure. Processing the semiconductor structure may include sawing the semiconductor structure and/or scrubbing the semiconductor structure with pressurized water. The oxidizing agent may include a peroxide, such as hydrogen peroxide, or another oxidizing agent.
