Abstract
PURPOSE:To obtain a high-quality compound semiconductor single crystal, by controlling the temperature gradient in a space above inner molten liquid of a crucible to a nearly uniform state in the growth of the crystal by Czochralski method and lowering the temperature in the furnace after transferring the grown crystal into the uniform temperature gradient zone in the cooling of the crystal after the completion of crystal growth. CONSTITUTION:A raw material is melted in a crucible 2 with heat and a crystal 10 is slowly pulled up from the molten liquid 7 to effect the growth of a compound semiconductor single crystal. The process is carried out by the following procedure. A zone having nearly uniform temperature gradient in vertical direction above the molten liquid 7 (e.g. the zone below the inflection point of the temperature gradient in the figure B) is formed by a heating means or by a heating and heat-insulation means (e.g. heater 4) disposed around the crucible 2 and, after the completion of pulling up of the crystal, the crystal 10 is transferred into the above uniform temperature gradient zone and then the temperature in the furnace is lowered to cool the crystal.
