    • The present invention employs the construction wherein a resistor heater is disposed inside a protective cylinder whose tip is open to a molten liquid packing zone of a crucible inside a pulling apparatus so that the resistor heater is above the tip of a lower portion and temperature setting can be made so as to be capable of fusing a starting material. Since the tip of the protective cylinder is positioned inside the molten liquid at the time of pulling of a single crystal, the gaseous phase portion inside the protective cylinder and the gaseous phase portion inside the pulling apparatus are separated apart by the molten liquid and are independent of each other and a starting material polycrystal rod loaded into the protective cylinder can be supplied to the molten liquid surface inside the crucible while being molten at the lower part of the protective cylinder by the resistor heater. In this manner, the single crystal whose impurity concentration is substantially uniform in the longitudinal direction can be grown continuously.
    • 本发明采用这样一种结构,其中电阻器加热器设置在保护筒内部,其顶端与拉制装置内的坩埚的熔融液体包装区域打开,使得电阻器加热器在下部的尖端上方,并且温度设定可以 使其能够熔化起始材料。 由于在拉制单晶时保护筒的尖端位于熔融液体内部,所以保护筒内部的气相部分和拉动装置内部的气相部分被熔融液体分开,并且是独立的 并且通过电阻加热器在保护筒的下部熔融时,可以将加载到保护筒中的原料多晶棒供给到坩埚内的熔融液面。 以这种方式,可以连续生长杂质浓度在纵向方向上基本均匀的单晶。
