A semiconductor light emitting device having high reliability and excellent light distribution characteristics can be provided with an n-electrode arranged on a light extraction surface on the side opposite to the surface whereupon a semiconductor stack is mounted on a substrate. A plurality of convexes are arranged on a first convex region and a second convex region on the light extraction surface. The second convex region adjoins the interface between the n-electrode and the semiconductor stack, between the first convex region and the n-electrode. The base end of the first convex arranged in the first convex region is positioned closer to a light emitting layer than the interface between the n-electrode and the semiconductor stack, and the base end of the second convex arranged in the second convex region is positioned closer to the interface between the n-electrode and the semiconductor stack than the base end of the first convex.

Method for manufacturing semiconductor light emitting device

A semiconductor light emitting device having high reliability and excellent light distribution characteristics is provided. Specifically, a semiconductor light emitting deviceis provided with an n-electrode, which is arranged on a light extraction surface on the side opposite to the surface whereupon a semiconductor stackis mounted on a substrate. A plurality of convexes are arranged on a first convex regionand a second convex regionon the light extraction surface. The second convex regionadjoins to the interface between the n-electrodeand the semiconductor stack, between the first convex regionand the n-electrode. The base end of the first convex arranged in the first convex regionis positioned closer to alight emitting layerthan the interface between the n-electrodeand the semiconductor stack, and the base end of the second convex arranged in the second convex regionis positioned closer to the interface between the n-electrodeand the semiconductor stackthan the base end of the first convex.
