Vorrichtung zur Erzeugung von Einkristallen hoher Qualität

摘要

A crucible for growing a single crystal therein has a seed crystal attachment portion and a peripheral portion surrounding the seed crystal attachment portion through a gap provided therebetween. The seed crystal attachment portion has a support surface for holding a seed crystal on which the single crystal is to be grown, and the support surface is recessed from a surface of the peripheral portion. The seed crystal is attached to the support surface to cover an entire area of the support surface. Accordingly, no poly crystal is formed on the seed crystal attachment portion, and the single crystal can be grown on the seed crystal with high quality.
