Patent ID: 7256483

Claim:
A light emitting device comprising: a light emitting diode (LED) portion comprising: a first epitaxial layer of a first conductivity type; a second epitaxial layer of a second conductivity type; an active layer disposed between the first and second epitaxial layers; a primary emission surface on a first side of the first epitaxial layer substantially parallel to the active layer; a package substrate on which the LED portion is mounted; and a metal interface, disposed between the package substrate and the second epitaxial layer, electrically connecting a conductor on the package substrate to the second epitaxial layer with no support substrate therebetween; wherein a nearest distance between the primary emission surface and a portion of the package substrate is not more than 50 microns, a lateral extent of the package substrate exceeds that of the LED portion and that of the metal interface, and the primary emission surface incorporates a light extraction feature.
