Method of producing sheets of crystalline material

摘要

A method of producing sheets of crystalline material is disclosed, as well as devices employing such sheets. In the method, a growth mask is formed upon a substrate and crystalline material is grown at areas of the substrate exposed through the mask and laterally over the surface of the mask to form a sheet of crystalline material. This sheet is separated, and the substrate can optionally be reused. The method has particular importance in forming sheets of crystalline semiconductor material for use in solid state devices.
