ABSTRACT:
An apparatus for pulling a monocrystalline ribbon-like body from a molten crystalline film via the EFG-process wherein a shaping or profile component having a capillary tube extending therethrough is positioned in contact with a crystalline melt so that a molten crystalline film forms on top of such component and a desired crystalline body is pulled therefrom. Surfaces of the profiling component in contact with the crystalline melt are composed of a material chemically inert with the crystalline melt, such as BeO or sapphire.
