Claim Text:
1. A light-emitting diode comprising: an N-type metal electrode; an N-type semiconductor layer contacting the N-type metal electrode; a P-type semiconductor layer; a light-emitting layer sandwiched between the N-type semiconductor layer and the P-type semiconductor layer; a low-contact-resistance material layer positioned on a part of the P-type semiconductor layer; a transparent conductive layer covering the low-contact-resistance material layer and the P-type semiconductor layer; a P-type metal electrode positioned on the transparent conductive layer; and a metal-indium contact layer positioned between the P-type semiconductor layer and the transparent conductive layer, wherein the low-contact-resistance material layer is embedded in the metal-indium contact layer and protrudes above a surface of the metal-indium contact layer into the transparent conductive layer.
