SINGLE CRYSTAL PRODUCING METHOD

摘要

A method for producing a single crystal by a Czochralski method in which a magnetic field is applied. The method is characterized in that the minimum magnetic field strength in the melt placed in the crucible is in the range above 2,000 G, the maximum magnetic field strength in the melt is in the range bellow 6,000 G, the maximum magnetic field gradient which is the quotient of the division of the difference between the maximum magnetic field strength and the minimum magnetic field strength by the distance is in the range below 55 G/cm, and a single crystal is pulled up. Thus, a high-quality single crystal can be produced with a high productivity.
