  • METHOD FOR PREPARING CRYSTAL OF NITRIDE OF METAL BELONGING TO 13 GROUP OF PERIODIC TABLE AND METHOD FOR MANUFACTURING SEMICONDUCTOR DEVICE USING THE SAME
    Publication number: 20100139551
    Abstract: A Periodic Table Group 13 metal nitride crystal is grown by causing a reaction of a Periodic Table Group 13 metal phase with a nitride-containing molten salt phase to proceed while removing a by-product containing a metal element except for Periodic Table Group 13 metals, from the reaction field. According to this process, a high-quality Periodic Table Group 13 metal nitride bulk crystal can be produced under low pressure or atmospheric pressure.
