  • Patent number: 10158047
    Abstract: Disclosed is a semiconductor light emitting device including: a plurality of semiconductor layers; a first non-conductive reflective film formed on the plurality of semiconductor layer to reflect light from the active layer, wherein the first non-conductive reflective film includes multiple layers and has a first incident angle as the Brewster angle; a second non-conductive reflective film formed on the first non-conductive reflective film to reflect light transmitted through the first non-conductive reflective film, wherein the second non-conductive reflective film includes multiple layers, with part of which being made of a different material from the first non-conductive reflective film, and has a second incident angle as the Brewster angle, different from the first incident angle; and an electrode electrically connected to one of the plurality of semiconductor layers.
    Type: Grant

  • Patent number: 10032960
    Abstract: Disclosed is a semiconductor light emitting device including: multiple semiconductor layers including a first semiconductor layer, a second semiconductor layer, and an active layer; an electrode electrically connected with the multiple semiconductor layers; a light absorption barrier disposed about at least the electrode; and a non-conductive reflective film adapted to cover the multiple semiconductor layers, the light absorption barrier and the electrode and to reflect light from the active layer, wherein the non-conductive reflective film has an abnormal region of a lower reflectivity around the electrode due to a height difference between the light absorption barrier and the electrode, wherein a portion of the non-conductive reflective film exposed from the electrode is made longer than the abnormal region as seen in a cross-sectional view of the electrode.
