ABSTRACT:
This invention relates to a method for growing semi-insulating III-V compound semiconductor crystals on a substrate by means of an epitaxially crystallizing process in the liquid state, which comprises the steps of:
A. placing a saturated solution of a III-V compound in a reaction tube,
B. carrying out a heating of the solution in the atmosphere of H.sub.2 gas, and
C. growing a crystal of the III-V compound on the substrate in the liquid phase at a temperature below the melting point of the III-V compound while keeping the vapor pressure of the V Group element under a predetermined value in the reaction tube.
