The GaAs crystal rate is controlled to 2mu/hour, the flow rate of the TMG to 7ml/min, and the flow rate of the Cp2Mg to 100ml/min at this time. The TMG is switched to the discharge pipe upon lapse of 30 minutes thereafter and the growth is interrupted for 10 seconds. Only the Cp2Mg is passed and again the TMG is introduced into the reaction tube to execute the crystal growth for 2 seconds. This cycle is repeated 270 times. The crystal growth is thereafter executed for 30 minutes by introducing the TMG and the Cp2Mg into the reaction tube.
