摘要: A semiconductor light-emitting device is disclosed. The semiconductor light-emitting device comprises a multilayer epitaxial structure disposed on a semiconductor substrate. The semiconductor substrate has a predetermined lattice direction perpendicular to an upper surface thereof, wherein the predetermined lattice direction is angled toward [0 11] or [01 1] from [100], or toward [011] or [0 11] from [ 100] so that the upper surface of the semiconductor substrate comprises at least two lattice planes with different lattice plane directions. The multilayer epitaxial structure has a roughened upper surface perpendicular to the predetermined lattice direction. The invention also discloses a method for fabricating a semiconductor light-emitting device.
