Patent ID: 7787512

Claim:
A light-emitting element assembly comprising: (A) a support substrate having a first surface, a second surface facing the first surface, a recessed portion formed in the first surface, and a conductive material layer formed over the first surface and the inner surface of the recessed portion; and (B) a light-emitting element; wherein the light-emitting element has a laminated structure including (B-1) a first compound semiconductor layer of a first conductivity type which has a first surface and a second surface facing the first surface, (B-2) a light-emitting portion laminated on the first surface of the first compound semiconductor layer, and (B-3) a second compound semiconductor layer of a second conductivity type which is laminated on the light-emitting portion, at least the second compound semiconductor layer and the light-emitting portion constituting a mesa structure; the light-emitting element further includes (B-4) an insulating layer formed over at least the side surface of the mesa structure and the first surface of the first compound semiconductor layer, (B-5) a second electrode formed over the top of the second compound semiconductor layer and the insulating layer, and (B-6) a first electrode formed on the second surface of the first compound semiconductor layer; the mesa structure of the light-emitting element is placed in the recessed portion so that the conductive material layer and the second electrode are in at least partial contact with each other; and light emitted from the light-emitting portion is emitted from the second surface side of the first compound semiconductor layer.
