Abstract
A semiconductor light-emitting device includes a substrate having an upper surface and a plurality of bumps positioned over the upper surface in a periodic manner, a first conductive type semiconductor layer positioned over the substrate, a light-emitting structure positioned over the first conductive type semiconductor layer, and a second conductive type semiconductor layer positioned over the light-emitting structure. The first conductive type semiconductor layer includes a plurality of protrusions each facing a portion of the substrate between the bumps, the protrusions are positioned in a ring manner at a peripheral region of the first conductive type semiconductor layer, and the protrusions are spaced apart from the bumps.
