Abstract
A method of producing single crystals is characterized in that in withdrawing a semiconductor or dielectric material from its molten state while allowing it to grow into a single crystal solid, a die heated to a temperature higher than the solidifying point of the melt is disposed at the melt withdrawing outlet and the single crystal is withdrawn through the die.
