Abstract:
1. A method of manufacturing a nitride semiconductor light emitting device comprising: growing an n-type nitride semiconductor layer including a multi-layered nitride semiconductor stacked structure by organic metal vapor deposition in a carrier gas containing nitrogen at a growth temperature of 500 to 1000° C., the multi-layered nitride semiconductor stacked structure comprising at least two layers each including a first nitride semiconductor layer and a second nitride semiconductor layer, wherein said first nitride semiconductor layer comprises n-type impurity and said second nitride semiconductor layer comprises undoped material or n-type impurity at a concentration lower than the n-type impurity of the first nitride semiconductor layer; forming an active layer over the n-type nitride semiconductor layer; and stacking a p-type nitride semiconductor layer over the active layer wherein a thickness of each of said first nitride semiconductor layer and said second nitride semiconductor layer is from 5 to 20 nm.
