ABSTRACT:
A method of making a light emitting diode (LED) is disclosed. The LED of the present invention comprises a semiconductor layer of a first polarity, an active layer, and a semiconductor layer of a second polarity stacked from bottom to up, wherein a stacked structure at least composed of the active layer and the semiconductor layer of the second polarity have a side with a wave-shape border in a top view of the LED and/or at least one valley, thereby increasing the efficiency of emitting the light to the outside of the LED.
