| titleOfInvention | Nitride semiconductor laminate and light emitting device using the same |
| abstract | The present invention provides a semiconductor laminate that can realize a light-emitting element that emits deep ultraviolet rays and has a low forward drive voltage and is unlikely to crack even if the buffer layer is thick. A template substrate, an aluminum gallium nitride layer, in which a buffer layer made of aluminum nitride having a thickness of 2 μm or more and 4 μm or less is formed in contact with a semiconductor laminated body in contact with an upper surface of a base substrate made of sapphire having a c-plane as an upper surface And a superlattice layer formed by alternately laminating aluminum nitride layers, an undoped aluminum gallium nitride layer, a first composition gradient layer whose aluminum ratio is gradually decreased upward, and an n-type impurity doped aluminum gallium nitride layer. A second composition gradient layer whose aluminum ratio is gradually decreased upward, a nitride semiconductor multilayer body comprising a group III nitride, an active layer having a light emitting layer emitting deep ultraviolet light, and a p-side layer sequentially laminated; To do.
