Claim 18:
19. A method for making a light emitting diode, comprising the steps of:
forming a first type semiconductor layer having an upper surface;
forming a stress relief layer on the upper surface of the first type semiconductor layer, the stress relief layer including at least one first repeating unit that contains a first well layer and a first barrier layer which are alternately stacked;
forming an active layer on the stress relief layer opposite to the first type semiconductor layer, the active layer including at least one second repeating unit that contains a second well layer and a second barrier layer which are alternately stacked;
forming a second type semiconductor layer on the active layer opposite to the stress relief layer; and
electrically connecting a first electrode to the first type semiconductor layer and electrically connecting a second electrode to the second type semiconductor layer,
wherein, the first well layer is made of a material including In; the second well layer is made of a material including In; the second barrier layer is formed with multiple sub-layers, each of the sub-layers being made of a material including Al.
