Abstract A process for producing a crystal article comprises the steps of: forming on a substrate surface a layer (S) comprising a different material (S) providing a nucleation density of the crystal nucleus to be formed sufficiently smaller than the amorphous material (L) constituting the substrate surface, forming an opening on said layer (S) so that the exposed portion of said substrate surface may have an area sufficiently small to the extent that a single crystal may grow only from the single crystal nucleus formed, permitting a single crystal to grow on the exposed portion of the substrate surface at said opening with the single crystal nucleus as the center, and flattening the surface of the grown single crystal by removing a part thereof.
