Abstract

See full text

A casting device for producing semiconductor material foil includes a casting frame and a substrate band. The casting frame is arranged for holding a molten semiconductor material and includes sidewalls of which an exit sidewall is located at an output position for the semiconductor material foil. The exit side wall is provided with an exit slit. The casting device further includes a local force exerting means to exert at the location of the exit slit a locally enlarged external force on the molten semiconductor material to enlarge an outer pressure on the molten material at the exit slit.
