Abstract
PURPOSE: To easily obtain a platelike crystal having a uniform composition by connecting a melt system to a crystal manufacturing system with a slitlike passage, making the pressure of the former system higher than that of the latter system to raise the melt through the passage, and bringing the melt into contact with a seed crystal.
CONSTITUTION: A crucible 5 is placed in a melt system composed of an upper lid 8 having a slit and a lower lid 9 in a vertically movable state. Starting material 6 for a melt and a liq. sealant 7 are put in the crucible 5, the material 6 is melted by heating, and a crucible moving shaft 16 is pushed up so that the lower part of the slit of the lid 8 is well soaked in the melt 6. The internal pressure of the melt system is then raised so that the melt 6 reaches the upper part of the slit, and after bringing a seed crystal 18 fixed to the tip of a crystal pulling shaft 17 into contact with the melt 6 at the upper part of the slit, the shaft 17 is raised at a constant speed to manufacture a platelike crystal 20.
