Abstract: PURPOSE:To improve a non-dislocation rate by disposing a heater for heating and a magnetic field generator around a crucible device housed in a pulling up furnace and rotating a heater for heating. CONSTITUTION:An inert gas, such as Ar, is supplied from a pulling up hole 21 in directions B20, B21, B30, B31 from an arrow direction B1 when the air is discharged therefrom by a prescribed amt. After the gas is moved around the crucible 30 and the heater 40 for heating, the gas is discharged from a discharge hole 22. The crucible device 30 is gently rotated in the direction of an arrow X1 by a crucible rotating device 34 and is moved in an arrow X2 direction so as to maintain the liquid height of a molten semiconductor material W. The heater 40 for heating is rotated in the direction of an arrow Y1 by a heater rotation driving device 44. A member 21A for pulling up is hung down where the semiconductor material W melts sufficiently. The semiconductor seed crystal mounted to the front end thereof is immersed into the molten semiconductor material W and is then pulled up to grow and form the semiconductor single crystal M. The molten semiconductor material W in a quartz crucible 31 of this time receives the magnetic field of a magnetic field generator 50 and since the heater 40 for heating rotates, the fluctuation in temp. is suppressed. Since convection is uniformized, the non-dislocation rate of the semiconductor single crystal M is improved.
