Patent ID: 8502257

Claim:
A light-emitting diode package, comprising: a substrate; a cavity disposed in the substrate, wherein the cavity has a depth of 30 μm to 150 μm; a first metal layer disposed over the substrate and in the cavity; an insulating layer disposed between the first metal layer and the substrate; a multi-layered metal structure disposed between the first metal layer and the insulating layer; a solder layer disposed on the first metal layer; a light-emitting diode chip disposed on the solder layer, wherein the light-emitting diode chip comprises a conductive substrate, a contact disposed on the conductive substrate and a multilayered epitaxial structure disposed on the contact, and wherein the conductive substrate is adjacent to the solder layer; and a second metal layer disposed between the conductive substrate of the light-emitting diode chip and the solder layer.
