ABSTRACT:
Method of and apparatus for manufacturing a single crystal compound semiconductor in a boat, whereby the melt forming the crystal is maintained at a higher temperature at its surface in contact with the bottom of the boat, than at its free surface in order that solidification of the melt begins at its free surface. Uniform crystallinity without structural defects or impurities is obtained.
