In inverted Stepanov apparatus, silicon is melted in vee-shaped crucible that has long narrow slot at bottom of vee. Molten silicon flows from slot at a rate controlled by fluid pressure. As it emerges, it cools and solidifies to form a continuous ribbon. To eliminate surface-tension effects, crucible walls are made of a material that liquid silicon does not wet.
