APPARATUS FOR MANUFACTURING POLY CRYSTALINE SILICON INGOT FOR DOOR OPEN/CLOSE DEVICE HAVING A WING TYPE

摘要

PURPOSE: An apparatus for manufacturing a poly-crystal silicon ingot is provided to prevent silicon growth defects by reducing thermal imbalance. CONSTITUTION: A crucible(200) receives silicon materials. A cooling plate(400) discharges heat for growing melt silicon in the crucible. A door opening and closing device(500) is formed between the crucible and the cooling plate and controls heat discharge. The door opening and closing device includes one or more wings(510). A driving unit(600) rotates the wing to control heat discharge between the cooling plate and the crucible.
