Abstract: PROBLEM TO BE SOLVED: To grow an epitaxial layer without permitting the residual melt or crystal core to adhere by slightly melting back the surface of the liquid phase epitaxial layer by increasing the temperature of the molten solution to the temperature that meets melt back condition after the completion of crystal growing. SOLUTION: The crystal growing of a liquid phase epitaxial layer is started by permitting a growing substrate 3 to make contact with molten solution 7, under the condition that a crystal layer on the surface of the growing substrate 3 does not melt back and the molten liquid is subcooled. Then, after completing the crystal growing of the liquid phase epitaxial layer by separating the growing substrate and the molten solution 7, the temperature of the molten solution is increased to the temperature near the liquefying temperature that meets the melt back condition. Then, the molten solution 7 is brought into contact with the growing substrate 3, and the surface of the liquid phase epitaxial layer is slightly melted back.  Thus, no residual melt nor crystal nucleus is left on the surface of the obtained liquid phase epitaxial layer, and a large area compound semiconductor crystal with excellent morphology is obtained at low cost.
