Abstract

PURPOSE:To obtain an ingot having good oriented crystal by holding as forming molten silicon column on the silicon ingot in an induction coil under inert gas atmosphere and cooling as descending the silicon ingot while supplying raw material silicon. CONSTITUTION:The molten silicon column 6 is formed and held on the silicon ingot 12 by electromagnetic force in the induction coil 7 under the inert gas atmosphere. The silicon ingot 12 is descended while supplying the raw material silicon 9 and the heat of the molten silicon column 6 is conducted with a cooling body 13 sequentially arranged at lower part. At the time of starting the casting, a seed ingot for silicon is inserted in the induction coil 7 and the molten silicon column 6 is initially formed on the seed ingot. By the casting with electromagnetic induction, the molten column 6 is formed without contacting with the induction coil 7 caused by resiliency between the casting product and the induction coil. As the silicon has big difference between electric resistances at the melting-state and solid-state, the exothermic phenomenon is scarcely generated at the solid part and it can sufficiently by indirectly cooling. By this method, the good oriented crystal is obtd. and the contamination is perfectly prevented and the product having good quality can be obtd.
