| 20120018732 | INSIDE REFORMING SUBSTRATE FOR EPITAXIAL GROWTH; CRYSTAL FILM FORMING ELEMENT, DEVICE, AND BULK SUBSTRATE PRODUCED USING THE SAME; AND METHOD FOR PRODUCING THE SAME - Sapphire substrates are used chiefly for epitaxial growth of nitride semiconductor layers, to provide a sapphire substrate of which the shape and/or amount of warping can be controlled efficiently and precisely and of which substrate warping that occurs during layer formation can be suppressed and substrate warping behavior can be minimized, to provide nitride semiconductor layer growth bodies, nitride semiconductor devices, and nitride semiconductor bulk substrates using such substrates, and to provide a method of manufacturing these products. Reformed domain patterns are formed within a sapphire substrate and the warp shape and/or amount of warping of the sapphire substrate are controlled by means of multiphoton absorption by condensing and scanning a pulsed laser through a polished surface of the sapphire substrate. When nitride semiconductor layers are formed using sapphire substrates obtained by means of this invention, substrate warping during layer formation is suppressed and substrate warping behavior is minimized so that layer quality and uniformity are improved and the quality and yield of nitride semiconductor devices is increased. | 01-26-2012 |
