Abstract
A semiconductor light-emitting device comprises a substrate, a buffer layer, an n-type semiconductor layer, a conformational active layer and a p-type semiconductor layer. The n-type semiconductor layer includes a first surface and a second surface, and the first surface directly contacts the buffer layer. The second surface has a plurality of recesses, and a conformational active layer formed on the second surface and within the plurality of recesses. Therefore, the stress between the n-type semiconductor layer and the conformational active layer can be released with the recesses.
