Abstract:
An apparatus for making an SiC single crystal in which the SiC single crystal is formed, said apparatus comprising:an Si-disposing section in which solid Si is disposed; a seed-crystal-disposing section in which a seed crystal of SiC is disposed; a synthesis vessel adapted to accommodate said Si-disposing section, said seed-crystal-disposing section, and carbon; heating means adapted to heat said Si-disposing section and said seed-crystal-disposing section, wherein, at an upper face of said Si disposed in said Si-disposing section, a shield made of carbon quartz, or SiC having passage holes that allow said Si evaporated by said heating means to pass therethrough is disposed; and a control section for controlling said heating means, wherein said Si evaporated by said heating means is adapted to reach said seed-crystal-disposing section.
