摘要： A semiconductor light emitting device includes a first conductive semiconductor layer including a V-shaped recess in a cross-sectional view. An active layer is disposed on the first conductive semiconductor layer, conforming to the shape of the V-shaped recess. An intermediate layer is disposed on the active layer and is doped with a first impurity. A second conductive semiconductor layer is disposed on the intermediate layer. The intermediate layer includes a first intermediate layer and a second intermediate layer. The first intermediate layer is disposed on the active layer, conforming to the shape of the V-shape recess. The second intermediate layer is disposed on the first intermediate layer and includes a protrusion to fill the V-shaped recess.

摘要： A method of manufacturing a nitride semiconductor light emitting device which includes forming an n-type semiconductor layer, forming an active layer on the n-type semiconductor layer, forming a superlattice layer by alternately stacking at least two nitride layers made of InxAlyGa(1-x-y)N (0≦x≦1, 0≦y≦1, and 0≦x+y≦1) having different energy bandgaps from each other and doped with a p-type dopant, and forming a p-type semiconductor layer on the superlattice layer. The forming of the superlattice layer is performed by adjusting a flow rate of a p-type dopant source gas to reduce the flow rate in a growth termination period of the superlattice layer by no greater than about half of the flow rate in a growth initiation period of the superlattice layer while being doped with the p-type dopant.
