Abstract:
1. A method for manufacturing a nitride semiconductor light emitting device, the method comprising: forming a resist pattern on a first nitride semiconductor layer formed above a substrate, wherein said resist pattern has a plurality of projections, wherein adjacent ones of said projections are continuous with each other, and wherein an inclination angle of an upper surface of said resist pattern relative to a substrate surface changes smoothly between said adjacent projections; etching said first nitride semiconductor layer by using said resist pattern as a mask to transfer said resist pattern to said first nitride semiconductor layer; and forming an active layer on said patterned first nitride semiconductor layer; wherein said active layer includes a multiple quantum well structure including a plurality of well layers, and wherein a maximum inclination angle of an upper surface of a lower well layer is steeper than a maximum inclination angle of an upper well layer.
