PROBLEM TO BE SOLVED: To provide a method for reutilizing silicon offcuts at a low cost.;SOLUTION: The method for reutilizing silicon offcuts includes: a cutting step of cutting the upper surface, the side surface and the bottom surface of a polysilicon ingot to obtain a polysilicon block, and to obtain upper surface offcuts, side surface offcuts and bottom surface offcuts; and a refining step of refining the upper surface offcuts into refined upper surface offcuts by the step different from the bottom surface offcuts, wherein the refined upper surface offcuts and the bottom surface offcuts are used as a raw material silicon.;COPYRIGHT: (C)2013,JPO&INPIT
