Abstract:
A lighting emitting diode including: an n side layer and a p side layer formed by nitride semiconductors respectively; an active layer comprising a nitride semiconductor is between the n side layer and the p side layer; wherein, the n-side layer is successively laminated by an extrinsically-doped buffer layer and a compound multi-current spreading layer; the compound multi-current spreading layer is successively-laminated by a first current spreading layer, a second current spreading layer and a third current spreading layer; the first current spreading layer and the third current spreading layer are alternatively-laminated layers comprising a u-type nitride semiconductor layer and an n-type nitride semiconductor layer; the second current spreading layer is a distributed insulation layer formed on the n-type nitride semiconductor layer; and the first current spreading layer is adjacent to the extrinsically-doped buffer layer; and the third current spreading layer is adjacent to the active layer.
