Abstract

PURPOSE: A heater of double structure is set around the outer surface of the crucible and the heater is vertically moved to control the neighborhood of the crucible to the prescribed temperature distribution, thus growing high-quality single crystals.
CONSTITUTION: A resistance heater of two-step and double structure is set concentrically around the outer surface of the crucible 43 and the outside heater is extended over the inside heater to form a cylindrical heater consisting of the lower heater 44B and the upper heater 44A. Both heaters 44A and 44B are provided with plate electrodes on the bottoms and the electrodes are controlled to move both heaters 44A and 44B vertically. Thus, the position of the crusible 43 relating to both heaters 44A and 44B is changed and simultaneously, the power input to both heaters are controlled independently to control the temperature distribution near the crucible 43 and the single crystal is pulled up.
