Method of holding a monocrystal and method of growing the same

摘要

There is disclosed a Czochralski method in which a seed crystal in contact with material melt is pulled, while being rotated, so as to grow a monocrystal, and a part of the crystal being grown is mechanically held during the pulling operation. The crystal is mechanically held in such a way that the weight (W kg) of the crystal satisfies the following Formula (1): $where\; D\; designates\; the\; minimum\; diameter\; (mm)\; of\; a\; neck.\; This\; makes\; it\; possible\; to\; pull\; a\; heavy\; monocrystal\; safely\; and\; reliably.$
