  • Vertical nitride based semiconductor light emitting device having improved light extraction efficiency
    Patent number: 8373184
    Abstract: The invention provides a nitride semiconductor light emitting device. In the invention, a first conductivity-type nitride semiconductor layer is formed on a conductive substrate having light transmissibility. An active layer is formed on the first conductivity-type nitride semiconductor layer. Also, a second conductivity-type nitride semiconductor layer is formed on the active layer. Further, a conductive light scattering layer made of a conductive material is formed on an underside of the substrate. The conductive light scattering layer has light transmissibility of 70% or more and has a rough pattern formed on an outer surface to scatter light.

  • Method of growing non-polar m-plane nitride semiconductor
    Patent number: 7645688
    Abstract: A method of growing a non-polar m-plane nitride semiconductor. A (11-23) plane sapphire substrate is prepared, and a non-polar (10-10) nitride semiconductor is grown on the sapphire substrate. The present invention can also be applied to a method for manufacturing other m-plane hexagonal semiconductors.
