Abstract:
A method for manufacturing polysilicon, according to the present invention, is capable of manufacturing polysilicon with high purity more efficiently in such a manner that a high-temperature and high-speed air stream is formed at the center of a reaction tube, and a high-temperature region may be formed by a vortex formed by the high-temperature and high-speed air stream, so that a raw gas supplied from the side wall of the reaction tube flows by the guiding of the vortex, thereby increasing a stay time and a reaction time of the raw gas within the reaction tube. Furthermore, since the inner wall of the reaction tube is provided with a heat release means, the rapid cooling of a silicon crystal deposited on the inner wall of the reaction tube can induce a columnar crystal in which the silicon crystal is solidified in a direction perpendicular to a crystal face, and it is easy to desorb the silicon crystal produced by rapid heat release via the inner wall of the reaction tube.

Claim (Index 3):
The method for manufacturing polysilicon according to  claim 1 , further comprising a heat releasing means for cooling the inner wall of the reaction tube, such that heat is released from the center of the reaction tube through the inner wall of the reaction tube, and silicon crystal is formed by directional solidification in which silicon crystal are formed in a direction opposite to the direction of heat release.
