发明名称 Semiconductor light emitting device having an electrode made of a conductive oxide
摘要 A semiconductor light emitting device with improved efficiency in extracting light is provided. The semiconductor light emitting device comprises a first conductive type semiconductor layer, a light emitting layer, and a second conductive semiconductor layer stacked in this order, electrodes respectively connected to the first and second conductive semiconductor layers, the electrode connected to the second conductive type semiconductor layer comprising a lower conductive oxide film and an upper conductive oxide film disposed on the lower conductive oxide film, and a metal film disposed only on the upper conductive oxide film. The upper and lower conductive oxide films comprise an oxide including at least one element selected from the group consisting of zinc (Zn), indium (In), tin (Sn), and magnesium (Mg).
