Abstract
A semiconductor light-emitting device comprises an N-type semiconductor layer, an active layer formed on the surface of the N-type semiconductor layer, a P-type semiconductor layer formed on the surface of the active layer, and a reflective layer formed on the surface of the P-type semiconductor layer. A plurality of ohmic contact blocks with electrical properties of ohmic contact are on the surface of the reflective layer adjacent to the P-type semiconductor layer, and the remaining part of the surface acts as the reflective regions with higher reflectivity, and the reflective regions can effectively reflect the light generated from the active layer.
