Abstract:
1. A process of heat-treating II-VI compound semiconductors, the process comprising: (a) placing at least one II-VI compound semiconductor whose surface is in contact with aluminum in a heat-treating chamber that (i) has an inside surface formed by at least one material selected from the group consisting of pyrolytic born nitride, hexagonal-system boron nitride, sapphire, alumina, aluminum nitride, and polycrystalline diamond, and (ii) has a communication hole; (b) placing the heat-treating chamber in an outer container made of quartz; (c) evacuating the outer container and the heat-treating chamber with a vaccum pump; and (d) heat-treating the II-VI compound semiconductor or semiconductors in the heat-treating chamber containing a gaseous atmosphere containing the group II element constituting part of the II-VI compound semiconductor or semiconductors.
