Abstract
A device for manufacturing a SiC single crystal includes: a raw material gas introduction pipe; a raw material gas heat chamber having a raw material gas supply passage for heating the gas in the passage; a reaction chamber having a second sidewall, an inner surface of which contacts an outer surface of a first sidewall of the heat chamber, and having a bottom, on which a SiC single crystal substrate is arranged; and a discharge pipe in a hollow center of the raw material gas heat chamber. The supply passage is disposed between an outer surface of the discharge pipe and an inner surface of the first sidewall. The discharge pipe discharges a residual gas, which is not used for crystal growth of the SiC single crystal.
