Patent ID: 8357951

Claim:
An LED (light emitting diode) chip comprising: a substrate; a first conduction layer formed on a top surface of the substrate; a second conduction layer formed on the first conduction layer; and an active layer; wherein the first conduction layer surrounds a bottom surface and a circumferential surface of the second conduction layer, light being generated between the first and second conduction layers when a voltage is applied between the first and second conduction layers; wherein the active layer is sandwiched between the first conduction layer and the second conduction layer, wherein the first conduction layer engages with a bottom surface and a circumferential surface of the active layer, and the active layer engages with the bottom surface and the circumferential surface of the second conduction laver; and wherein a top surface of the first conduction layer, a top surface of the active layer, and a top surface of the second conduction layer are coplanar with each other.
