A crystal article comprises a substrate having an insulating amorphous surface and monocrystal formed on the substrate. The monocrystal is formed by providing a primary seed in the form of a film with an area 100 mu m<2> or less arranged in a desired pattern on the surface of the substrate acting as a non-nucleation surface with a small nucleation density, then subjecting the primary seed to thermal treatment to convert it to a monocrystalline seed, and subsequently subjecting the monocrystalline seed to crystal growth treatment to allow a monocrystal to grow beyond the monocrystalline seed and cover the non-nucleation surface. |
