Zusammenfassung:	In the production of a semi-conductor foil by solidification of a liquid semi-conductor on a horizontal support, the improvement which comprises positioning a molding body on the horizontal support, supplying the liquid semi-conductor to the molding body, and effecting relative movement between the molding body and support in a direction parallel to the support. Thereby fault-free silicon foils can readily be produced.
