Abstract:
1. A method of fabricating a nitride semiconductor light-emitting device, the device including: a single-layer substrate; a single-layer nitride semiconductor layer laid on a top of the single-layer substrate; a defect-concentrated region in the single-layer substrate or the single-layer nitride semiconductor layer; a low-defect region, separate from the defect-concentrated region, in the single-layer substrate or the single-layer nitride semiconductor layer; a depression in the defect-concentrated region or the low-defect region; and an engraved region in the single-layer substrate or the single-layer nitride semiconductor layer, obtained by engraving a portion including the depression, the method of fabricating the device comprising: forming the depression; and forming the engraved region by engraving the portion including the depression.
