ABSTRACT:
In a single-crystal manufacturing method, after a single crystal is grown, the crystal is separated from the molten melt and gradually cooled while suspended immediately above the surface of the melt. During this cooling, a measure, which produces solidification of the melt, is locally applied. As a result, the solidification of the melt is selectively forced so that at least the melt forms a crust and prevents the crystal, should it fall, from becoming immersed in molten melt. This measure also protects the crystal from any sudden release of heat such as tends to occur if the melt becomes supercooled prior to the onset of crystallization.
