Vertical light emitting diode structure with high current dispersion and high reliability
Abstract:
A vertical light emitting diode structure with high current dispersion and high reliability comprises a conductive substrate with a central region and a side region; a light emitting semiconductor layer is disposed on the central region; an ohmic contact metal layer is disposed at a center of the light emitting semiconductor layer; an N-type electrode is disposed at the side region and is connected with the ohmic contact metal layer and the N-type electrode through an N-type electrode bridging structure; a working current is diffused from the center of the light emitting semiconductor layer to have high current dispersion, so that the problem of heat dissipation of local high current caused by the design that the N-type electrode is disposed on the edge can be solved.
