| titleOfInvention | Gallium nitride self-supported substrate, light-emitting device and manufacturing method therefor |
| abstract | There is provided a gallium nitride self-standing substrate made of a plate composed of a plurality of gallium nitride-based single crystal particles having a single crystal structure in an approximately normal direction. The gallium nitride self-standing substrate includes a step of preparing a poly-orientation crystal sintered body, a step of forming a seed crystal layer made of gallium nitride on the poly-orientation crystal sintered body so as to have a crystal orientation substantially following the crystal orientation of the polyoriented crystal sintered body, and A step of forming a layer consisting of a gallium nitride-based crystal having a thickness of 20 μm or more on the crystal layer to have a crystal orientation generally following the crystal orientation of the seed crystal layer, and removing the oriented polycrystalline sintered body to obtain a gallium nitride self-supporting substrate It can be manufactured by a method including a process. According to the present invention, it is possible to provide a gallium nitride self-standing substrate useful as an alternative material for a gallium nitride single crystal substrate, which is inexpensive and suitable for a large area. |
