SAPPHIRE SUBSTRATE AND METHOD FOR MANUFACTURING THE SAME AND NITRIDE SEMICONDUCTOR LIGHT EMITTING DEVICE |
摘要 |
A sapphire substrate having one principal surface on which a nitride semiconductor is grown, said one principal surface having a plurality of projections. Each of the projections has a generally pyramidal shape with a not truncated, more sharpened tip and with an inclined surface composed of a crystal growth-suppression surface that lessens or suppresses the growth of the nitride semiconductor and also which has an inclination change line at which an inclination angle discontinuously varies.
