Abstract: Elongated crystalline silicon rods are pulled from the melt in a crucible, using a seed crystal with a 110> or 110> (211)-orientation. The crystal pulling furnace has a puller rod with an upper surface which always retains a fixed amt. of fused metl material, and after the seed crystal has been dipped in the melt, the puller rod is moved upwards at a controlled speed. This produces elongated, pref. strip-shaped, silicon crystals which are distinguished by a smooth surface, a low defect density and exactly defined dimensions.

Abstract: METHOD AND APPARATUS FOR FORMING SILICON CRYSTALLINE BODIES Method and apparatus for forming an elongated silicon crystalline body using a specially designed capillary die. The method and apparatus uses a higher melt meniscus in the central region of the growth front than at the edges of the front. The edges of the top surface of the die are not concentric with the ribbon cross-section.
