ABSTRACT A method of, and device for, manufacturing semiconductor devices in which a layer of semiconductor material is provided on a main surface of a solid substrate by solidification of molten semiconductor material on the substrate surface. A substantially floating liquid mass of the semiconductor material is formed on a horizontal surface of a solid support and this liquid mass is contacted with a main surface, which surface is wettable by the liquid mass, of the solid substrate onto which the layer of semiconductor material is to be provided. The solid substrate has the form of a strip which is moved in its longitudinal direction along the liquid mass so that a liquid layer of semi- conductor material is formed on the strip and taken along with it. This liquid layer is then progressively solidified.
