  • MANUFACTURING APPARATUS OF SiC SINGLE CRYSTAL AND METHOD FOR MANUFACTURING SiC SINGLE CRYSTAL
    Publication number: 20130284083
    Abstract: A manufacturing apparatus for SiC single crystal has a control unit to control induction heating such that frequency f (Hz) of alternating current to be passed to the induction heating unit satisfies Formula (1); D1 (mm) is permeation depth of electromagnetic waves into a side wall of a crucible by the heating unit, D2 (mm) is permeation depth of electromagnetic waves into a SiC solution, T (mm) is thickness of the crucible side wall of the crucible, and R (mm) is crucible inner radius: (D1?T)×D2/R>1??(1) where, D1 is defined by Formula (2), and D2 by Formula (3): D1=503292×(1/(f×?c×?c))1/2??(2) D2=503292×(1/(f×?s×?s))1/2??(3); ?c is electric conductivity (S/m) of the sidewall, ?s is electric conductivity (S/m) of the SiC solution; ?c is relative permeability of the sidewall, and ?s relative permeability of the SiC solution.
