Abstract:
A high brightness light emitting diode having a distributed contact area, comprising;a first electrode; a semiconductor substrate formed on said first electrode; a first cladding layer of a first conductivity type formed on said semiconductor substrate; an active layer formed on said first cladding layer; a second cladding layer of a second conductivity type formed on said active layer; a window layer of a second conductivity type formed on said second cladding layer; a distributed contact area comprising a plurality of contact grains in the form of circular cylinders formed on said window layer; a transparent conductive layer formed over said distributed contact area and said window layer, the transparent conductive layer being in ohmic contact with said distributed contact area and a Shottky barrier being formed between the transparent conductive layer and said window layer; and a second electrode formed on said transparent conductive layer.
