摘要
PURPOSE: A continuous casting apparatus of a silicon ingot and a continuous casting method thereof are provided to reduce contamination due to metallic impurities by suppressing degradation of localized lifetime.;CONSTITUTION: A cooled crucible(7) continuously casts poly-crystal silicon by melting a silicon raw material. A top plate(10) fixes the cooled crucible. An induction coil(8) heats the silicon raw material charged inside of the cooled crucible by performing an electromagnetic induction process. A separation material(17) separates the inside and the outside of the cooled crucible. The separation material is comprised of silicon, SiC, quartz, alumina, or carbon.;COPYRIGHT KIPO 2012
