III-Nitride Semiconductor Light Emitting Device and Method for Manufacturing the Same

摘要

Disclosed herein is a IE-nitride semiconductor light emitting device comprising a plurality of nitride semiconductor layers including a substrate and an active layer deposited on the substrate, in which the substrate is provided with protrusions to let the lights generated in the active layer emit out of the light emitting device and each of the protrusions has a first scattering plane and a second scattering plane, which are not parallel to each other.
