摘要： A semiconductor device in which a strained-layer of super-lattice composed of two or more group II-IV semiconductors grown on an epitaxial growth layer formed on a surface of a semiconductor substrate. Since the strained-layer of super-lattice composed of two or more group II-VI semiconductors is present in the heterojunction of the heterostructure, it is possible to form a favorable heterostructure seminconductor layer, inhibiting the adverse effects of lattice mismatch.
