Summary: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; at least one indentation comprising a bottom part extending downward to reach the first semiconductor layer and exposing the first semiconductor layer; a first metal layer disposed on the second semiconductor layer, connecting to the first semiconductor layer at the bottom part of the indention; and an first insulating layer deposited on the second semiconductor layer and between the first metal layer and the second semiconductor layer to isolate the first metal layer from the second semiconductor layer.
