Abstract (en)
[origin: WO9931738A2] A channeled semiconductor LED is disclosed that is comprised of a substrate, upper and lower contact layers, the lower contact layer adjacent the substrate, and a light emitting region interposed between the upper and lower contact layers. One or more channels extend through the upper contact layer and the light emitting layer, the one or more channels defining LED sub-structures, and improving the luminous efficiency of the LED.
