ABSTRACT:
A process or method for the production of epitaxial layers on a monocrystalline substrate by moving a melt on a surface of the substrate, depositing the layer and then removing the remaining melt from the substrate characterized by the substrate being a crystal having two boundary edges, which are parallel to one another and in which no preferred edge growth occurs in a direction running at right angles to the boundary edges and pointing outward from the interior of the substrate crystal so that no portion of the melt will be retained as the melt is being removed after forming the layer.
