Patent ID: 7615796

Claim:
A light emitting diode, comprising: a substrate; an adhesive layer disposed on the substrate; a conductive layer disposed on the adhesive layer, wherein the conductive layer has an upper surface and a lower surface, the distance between the upper surface and the substrate is greater than that between the lower surface and the substrate, and the upper surface has a first surface region, a second surface region, and a third surface region; a light emitting stack disposed on the first surface region, wherein the light emitting stack comprises: a first semiconductor stack; a light emitting layer on the first semiconductor stack; and a second semiconductor stack on the light emitting layer, and wherein the first semiconductor stack and the conductive layer is distinguishable; an electrode buffer layer disposed on the second surface region; a first electrode conformably formed around the electrode buffer layer, the first electrode extending downward and being in direct contact with the conductive layer in the third surface region; and a second electrode disposed on the light emitting stack.
