Abstract
A vertical light emitting diode (LED) assembly with current spreading material over one or more sidewalls of the LED is disclosed. In one embodiment, the vertical LED assembly includes an LED comprising a light emitting layer disposed between a first layer having a first conductivity type and a second layer have a second conductivity type. The vertical LED assembly further includes a substrate bonded to the LED and a first electrode disposed between the substrate and the LED and electrically coupled to the first layer of the LED. A second electrode is formed on a surface of the second layer of the LED opposite the first layer, and electrically coupled to the second layer. In one embodiment, the second electrode extends over one or more sidewalls of the LED. In one embodiment, the second electrode extends laterally beyond one or more sidewalls of the LED.
