发明名称 LIGHT EMITTING DIODE AND METHOD FOR IMPROVING LUMINESCENCE EFFICIENCY THEREOF
摘要 A light emitting diode comprising a semiconductor layer, a first electrode, a second electrode and a diamond-like carbon layer is provided. The semiconductor layer includes a first type doped semiconductor layer, a light emitting layer and a second type doped semiconductor layer. Wherein, the light emitting layer locates between the first type doped semiconductor layer and the second type doped semiconductor layer. The first electrode is electrically connected to the first type doped semiconductor layer. The second electrode is electrically connected to the second type doped semiconductor layer. The diamond-like carbon layer covers on the semiconductor layer and exposes at least a portion of the first electrode. Moreover, the exposed outer surface of the diamond-like carbon layer is a rough surface. Alternatively, other passivation layer with rough surface can be substituted for the diamond-like carbon layer.
