  • Light emitting diode
    Patent number: 6522063
    Abstract: A light emitting diode. The light emitting diode has a substrate that has two surfaces. On one surface, a distributed Bragg reflector, an n-type confining layer, an active layer, a p-type confining layer, a current spreading layer, a meshed Ohmic contact layer, a transparent conductive oxide layer and a front side electrode are formed. The other surface has a rear side electrode formed thereon. Via the meshed structure, the absorbing area of the Ohmic contact layer is reduced to avoid the light emitting from the active layer being greatly absorbed by the Ohmic contact layer. In contrast, the light intensity of the light emitting diode is increased.
    Type: Grant
