ABSTRACT:
A semiconductor light-emitting device includes a substrate having an upper surface and a plurality of bumps positioned on the upper surface, a first conductive type semiconductor layer positioned on the substrate, a light-emitting structure positioned on the first conductive type semiconductor layer, and a second conductive type semiconductor layer positioned on the light-emitting structure. In one embodiment of the present disclosure, each of the bumps has a top plane substantially parallel to the upper surface, the first conductive type semiconductor layer has a plurality of protrusions each facing a portion of the substrate between the bumps, and the protrusions are spaced apart from the bumps.
