Abstract:
1. A light emitting device comprising: a substrate; a layer of first conductivity type overlying the substrate; a light emitting layer overlying the layer of first conductivity type; a layer of second conductivity type overlying the light emitting layer; a conductive transparent layer overlying the layer of second conductivity type; a reflective metal layer overlying the conductive transparent layer, wherein the conductive transparent layer and the reflective metal layer provide electrical contact with the layer of a second conductivity type and comprise an area that is at least 50% of the device; and a plurality of contacts electrically contacting the layer of first conductivity type, wherein the light emitting device has a flip-chip configuration in which the plurality of contacts and the reflective metal layer are on the same side of the light emitting device and light is extracted through the substrate.
