Filed: 1980-05-01
Abstract: PURPOSE: In the liquid-phase epitaxial growth, the metal melt is previously baked at a temperature lower than the crystal growth one, then brought into contact with the base crystal, thus permitting the stable and high-purity growth of the epitaxial layer.  
     CONSTITUTION: In the liquid-phase epitaxial growth where the melt of the crystal material is brought into contact with the crystal base to grow the crystal on the base, the metal melt is previously baked in a reductive atmosphere at a temperature more than 100°C lower than the crystal growth one for more than 5hr. Then, the temperature is raised to higher than the crystal growth temperature and as cooled gradually, the melt is brought into contact with the base crystal to grow the epitaxial layer on the base. Since the metal melt is baked at a low temperature, the base crystal never suffers from heat damage and the impurities in the metal melt are removed, resultingly the possibility that silicon is included in the metal melt by the reaction between the quartz tube and the remaining oxygen is eliminated.
