Abstract
Provided is an ingot growing apparatus. The ingot growing apparatus includes a quartz crucible in which a silicon melt is stored, a graphite crucible in which the quartz crucible is accommodated, a crucible support supporting a lower portion of the graphite crucible, and a heater supplying heat into the graphite crucible. The graphite crucible comprises an inner body contacting the quartz crucible and an outer body disposed spaced a predetermined distance from the inner body, and an inert gas is injected between the inner body and the outer body to form an inert gas layer. According to an embodiment, when polysilicon is melted, the inside of the crucible may be thermally insulated to reduce a heater power, and concentration of degradation in a specific portion of an inner wall of the crucible may be prevented to prevent the crucible from being damaged by the degradation, thereby increasing a life-cycle of the crucible.
