ABSTRACT:
A liquid material such as molten silicon is stored in a crucible. A liquid material, which is identical to and held in the same conditions as the liquid material in the crucible, is continuously supplied from an auxiliary crucible to the crucible to keep constant the surface level of the liquid material in the crucible. The liquid material is continuously pulled up from the crucible at a predetermined speed while the liquid material is being solidified into a solid material such as a ribbon-like thin web of single-crystal silicon.
