Crystal growth method and apparatus

Abstract

A crystal growth method having the steps of: preparing a growth container having a vapor generating chamber VC provided with a source material 14, a growth chamber GC provided with a seed crystal 12, and a coupling portion 18 having a cross sectional area narrower than a cross sectional area of each of the vapor generating chamber and the growth chamber, the coupling portion coupling the vapor generating chamber and the growth chamber; and vapor-phase growing a single crystal on the seed crystal by forming a temperature gradient in the growth container and by maintaining the seed crystal in the growth chamber at a growth temperature and the source material in the vapor generating chamber at a vapor supply temperature higher than the growth temperature. A crystal having a diameter larger than that of a seed crystal can be formed easily.
