ABSTRACT:
A process for producing single crystals has been presented which enables the pulling up and growing of single crystals, without loss of accurate control of the oxygen concentration in the crystal, and with excellent dielectric strength of subsequently produced gate oxide films. The process of producing single crystals in accordance with this invention is characterized by confluence of the inert gas flows (33 and 32) once divided into outside and inside a heat resistant and heat insulative component (7).
