SINGLE CRYSTAL GROWER AND APPARATUS AND METHOD FOR SUPPLYING RAW MATERIAL TO IT

摘要

The present invention relates to a single crystal growing device capable of not only preventing damage to a crucible during the recharging of a solid fuel but also increasing pulling speed, and to a raw material supplying device and a raw material supplying method applied thereto. An embodiment of the present invention provides a single crystal growing device comprising: a chamber including a mounting hole provided at the top surface thereof; a crucible installed inside the chamber and having a raw material melted therein; a raw material supplying device detachably installed on the mounting hole and supplying raw material to the crucible; and a buffering member located in the crucible, for buffering raw material dropping from the raw material supplying device and seating the raw material in the crucible. The buffering member includes: a ring-shaped flange portion; a cylindrical main body portion having a diameter that progressively narrows downward from the flange portion, and a concavo-convex portion provided on the inner peripheral surface of the main body portion.
