PROCESS FOR THE MANUFACTURE OF COARSELY CRYSTALLINE TO MONOCRYSTALLINE SHEETS OF SEMICONDUCTOR MATERIAL ABSTRACT OF THE DISCLOSURE The invention provides a process for the manufacture of coarsely crystalline to monocrystalline sheets and/or plates of semiconductor material of preferred orientation. A meniscus of molten semiconductor material comes in contact with a moving, cooler substrate of the same coarsely crystalline to monocrystalline semiconductor material, during which, while transferring the preferred orientation, a thin sheet of the semiconductor material is pulled onto the substrate and, after cooling, becomes detached from the support. The substrate can be reused as often as desired.
