Abstract
A light emitting diode and a method of the same are provided. The light emitting diode includes a substrate with a first region and a second region, a first semiconductor layer, a light-emitting layer, and a second semiconductor layer. The light emitting diode further includes a plurality of vias, a first metal layer, a second metal layer, and a patterned passivation layer interposed between the second semiconductor layer and the first metal layer. The plurality of vias are located in the first region and penetrate through the second semiconductor layer and the light-emitting layer to expose part of the first semiconductor layer. The first metal layer is located in the first region, and electrically contacted with the first semiconductor layer through the plurality of vias. The second metal layer is located in the second region, and electrically contacted with the second semiconductor layer and electrically insulated from the first metal layer. The patterned passivation layer is configured to electrically isolate the first metal layer from the second semiconductor layer and the light-emitting layer.
