Abstract:
1. A method of fabricating a nitride semiconductor light emitting device, the method comprising: growing a first group III nitride semiconductor layer on a substrate, the first group III nitride semiconductor layer having a top surface formed as a group III rich surface exhibiting a group III polarity and a bottom surface formed as a N-rich surface exhibiting a N-polarity; selectively etching an N-polarity region in the top surface of the first group III nitride semiconductor layer; forming a second group III nitride semiconductor layer on the first group III nitride semiconductor layer to fill the etched N-polarity region; and forming a light emitting structure on the second group III nitride semiconductor layer, the light emitting structure including a first conductivity type nitride semiconductor layer, an active layer, and a second conductivity type nitride semiconductor layer.
