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 14):
The method for manufacturing polysilicon according to  claim 1 , wherein a silicon matrix is formed with silicon crystal precipitated by the raw gas and the silicon fine powder adsorbed on the surface of the inner wall of the reaction tube, and with the silicon matrix as a reaction surface, the adsorption of the silicon fine powder and the reaction of the raw gas occur, and thereby silicon crystal is precipitated on the silicon matrix.
