Abstract
PURPOSE: To obtain a high quality single crystal in high rate of production, using Czochralski method, by iradiating the molten material with ultrasonic radiation.
CONSTITUTION: A crucible 4 is charged with the raw material of crystal, and heated by the heater 7 to melt the raw material 5. Ultrasonic wave generated from the oscillator 1 by the circuit 2 is transmitted to the crucible 4 and the molten material 5 through the oscillation transmitting rod 3. The crystal is pulled up from the molten material5 at a high rate to obtain a high quality single crystal.
