ABSTRACT:
A method of heat treatment for purifying a Groups II-VI compound semiconductor and for producing a purity Groups II-VI compound semiconductor crystal using a sealed container placed a Groups II-VI compound semiconductor crystal as a raw material is disclosed. The process includes heating means applied to the sealed container having a temperature difference which has a high-temperature zone and a low-temperature zone into the sealed container, placing the raw material into the high-temperature zone of the sealed container, using a heat atom making an atmosphere of either a Group II element or a Group VI element, or a mixed atmosphere of either which is necessary to treat the Groups II-VI compound semiconductor into the sealed container, and using a Groups II-VI compound semiconductor as raw material.
