QUARTZ GLASS CRUCIBLE FOR PULLING SILICON MONOCRYSTAL AND METHOD OF MANUFACTURING THE SAME

摘要

A quartz glass crucible for pulling out a silicon monocrystal therefrom, capable of pulling a flawless silicon monocrystal therefrom and improving greatly the monocrystallinity of the silicon monocrystal, and a method of manufacturing the same. Specifically, a quartz glass crucible for pulling out a silicon monocrystal therefrom, comprising a crucible base member of a translucent quartz glass layer, and a transparent quartz glass layer formed on an inner surface of the crucible base member, wherein bubble expansion of not less than 0.5 mm in diameter does not occur within 1 mm of an inner surface of the crucible from which the silicon monocrystal has been pulled out.
