Light-emitting diode chip

Abstract

A light-emitting diode (LED) chip including a first semiconductor layer; an active layer disposed on the first semiconductor layer; a second semiconductor layer disposed on said active layer; one or a plurality of indentations, comprising a bottom part extending downward through the second semiconductor layer and the active layer to reach the first semiconductor layer and exposing the first semiconductor layer; a plurality of metal layers, comprising a first metal layer connecting to the first semiconductor layer through the bottom part, and a second metal layer deposited on the first metal layer; and an insulating layer formed between the first and the second metal layers, disposed on the indentation and covering the first metal layer, wherein the second metal layer comprises one or a plurality of recesses at a top surface thereof corresponding to the one or plurality of indentations.
