摘要： PROBLEM TO BE SOLVED: To provide both a method for pulling a silicon single crystal by which the silicon single crystal can stably be pulled with high reliability even when the pulling weight is increased by increasing the caliber and the length of a grown silicon single crystal ingot and an apparatus for pulling the silicon single crystal. SOLUTION: This method for pulling a silicon single crystal comprises dipping a seed crystal in a silicon melt, pulling the seed crystal, thereby growing a silicon single crystal ingot 9 at the rear end of the seed crystal, holding the silicon single crystal ingot 9 grown thereafter with a mechanical holding means and carrying out the pulling. In this case, the contact part of the means for performing the mechanical holding with the ingot 9 is a pillowy structure 17 deformable by an external force. Since the contact part is deformed along uneven parts on the surface of the ingot 9 when holding the ingot 9, the mechanical holding means can uniformly be brought into contact with the ingot 9 to uniformly disperse the applied pressing force throughout the whole contact part and hold the ingot 9 without causing trouble such as occurrence of a concentrated stress due to biased contact or the like.

摘要： PROBLEM TO BE SOLVED: To provide a method for pulling a silicone single crystal stably and in a high reliability even on increasing the pulling weight of the grown silicone single crystal ingot made to have a large diameter and large length, and also a device therefor. SOLUTION: This method for pulling a silicone single crystal is to immerse a seed crystal 7 into a melted silicone liquid and pulling the seed crystal for growing the silicone single crystal ingot 8 at the rear end part of the seed crystal and then perform the pulling of the grown silicone single crystal ingot by using a single crystal holding means 10 made as independently liftable from the seed pulling means. In this case, the holding of the silicone single crystal ingot is performed by a vacuum sucking force obtained by sucking an atmosphere in a sucked space formed by an opposing wall surface of the contacting part 16 of the holding means to the silicone single crystal ingot and the ingot surface by a vacuum pump 26 communicating with the sucked space through vacuum piping 19, 29, 23, 27.
