Abstract
A semiconductor LED and a method manufacturing the semiconductor LED are disclosed. The method can include: forming a light emitting structure, which includes an N-type semiconductor layer, an active layer, and a P-type semiconductor layer stacked together, on a substrate; processing a division groove in the shape of a dotted line from the direction of the substrate or from the direction of the light emitting structure; and dividing the substrate and the light emitting structure along the division groove by applying pressure to at least one of the substrate and the light emitting structure. Embodiments of the invention can prevent total reflection for light emitted through the sides, and as a result, the light emitting efficiency can be improved.
