III nitride semiconductor substrate for ELO |
| 摘要 |
A III nitride semiconductor substrate for ELO is provided for forming a III nitride film whose surface is controlled independent of the film's thickness. A III nitride underlayer including at least Al is directly formed on a base made of e.g. a sapphire single crystal, and not formed through a buffer layer formed at a low temperature. After that patterns made of e.g SiO2 are formed on the underlayer.
