  • Publication number: 20060261358
    Abstract: The present invention relates to a flip chip light emitting diode in which an n-type electrode is formed on an insulating layer so that a large light emitting area can be secured to thereby enhance a current-spreading effect and in which the n-type electrode serves as a light reflecting layer so that light is prevented from being transmitted into the rear surface to thereby enhance light emission efficiency.

  • Patent number: 7087985
    Abstract: In a nitride semiconductor LED having a light emitting structure, an n-doped semiconductor layer has a first region and a second region surrounding the first region, an active layer is formed on the second region of the n-doped semiconductor layer, and a p-doped nitride semiconductor layer is formed on the active layer. A p-electrode is formed on the p-doped semiconductor layer. An n-electrode is formed on the first region of the n-doped nitride semiconductor layer.
