Abstract
A light emitting diode is disclosed that includes an active structure formed of at least p-type and n-type epitaxial layers of Group III nitride on a conductive carrier substrate. A conductive bonding system joins the active structure to the conductive carrier substrate. A first transparent ohmic contact is on the active structure adjacent the conductive carrier substrate, a second transparent ohmic contact is on the active structure opposite the conductive carrier substrate, and a third ohmic contact is on the conductive carrier substrate opposite from the active structure.
