SINGLE CRYSTAL MANUFACTURING APPARATUS AND SINGLE CRYSTAL MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a single crystal manufacturing apparatus capable of independently controlling a temperature distribution around a growth surface and a temperature distribution of a raw material part, and a method for manufacturing the single crystal using the single crystal manufacturing apparatus.SOLUTION: A single crystal manufacturing apparatus 10a comprises: a crucible 20 for fixing a seed crystal 22 for growing a single crystal in the upper part and charging a raw material 24 for growing the single crystal in the lower part; a first heating part 30 for mainly heating the raw material 24; a perforated heat insulation member 40 arranged around the crucible 20 above the first heating part 30; and distance adjustment means for adjusting a distance between at least a part of the heat insulation member 40 and the first heating part 30. The single crystal can be manufactured by growing a single crystal on the growth surface of the seed crystal 22 while adjusting the distance between at least a part of the heat insulation member 40 and the first heating part 30 during its growth using the single crystal manufacturing apparatus 10a.
