Method of growing single crystal of compound semiconductors

摘要

A method of growing a single semiconductor crystal with a flat top. In order to grow a single flat top crystal, the InP crystal is pulled up after the temperature drop of the melt has almost stopped, at a point in time when a meniscus at the interface of solid-liquid can be seen over the whole circumference of the surface of the melt. This prevents a facet from appearing at the shoulder portion of the crystal, thus reducing the generation of twin crystals and drastically improves retension of single crystal formation.
