摘要： PROBLEM TO BE SOLVED: To manufacture a good quality silicon carbide single crystal free from inclusions at a high crystal growth speed even when the single crystal has such a large size that the diameter is ≥1 in and the thickness is ≥5 μm, in the manufacturing of the silicon carbide single crystal by a solution growth method comprising immersing an SiC seed crystal fixed to a seed stem in a solution of SiC in an Si or Si alloy melt in a rotating crucible, and growing an SiC single crystal layer on the SiC seed crystal by making SiC into a supersaturated state by the supercooling of at least solution around the seed crystal. SOLUTION: In a method for manufacturing the silicon carbide single crystal, the single crystal is grown while utilizing an accelerated crucible rotation technique wherein acceleration of the rotation of the crucible to a prescribed rotation number, retention at the rotation number and deceleration to a low or zero rotation number are repeated. The rotation direction of the crucible may be reversed at every acceleration. Further, the seed stem may be rotated in synchronization with the rotation of the crucible in the direction being the same with or reverse to that of the rotation of the crucible.
