    Abstract: There is provided a single crystal growth method which allows single crystal of an incongruent melting compound to be grown stable while controlling its growth orientation. The single crystal growth method comprises the steps of: holding polycrystal and seed crystal within a heating furnace; joining the polycrystal with the seed crystal; heating the polycrystal on the side opposite from the side where the polycrystal is joined with the seed crystal to form a melt zone; moving the melt zone to the side where the polycrystal is joined with the seed crystal so that the melt zone is in contact with the seed crystal to allow seeding; and growing single crystal by moving the melt zone which has been in contact with the seed crystal and been seeded to the opposite side from the side where the polycrystal is joined with the seed crystal.

    Abstract: A method and apparatus for producing crystalline ribbons by zone melting. Means for coupling electromagnetic energy into a film of material are provided to appropriately induce electrical currents in order to control and restrict the molten zone and suppress net loss of the heat of fusion from the balance of the ribbon in contact with the melt, thus controlling the thickness uniformity of the resulting ribbon. The heat of crystallization is selectively removed by a heat absorbing means from one end of the melt zone in a direction substantially perpendicular to the direction of pulling.

    Abstract: Semiconductor crystal films on a dielectric substrate are advantageously made by a zone melting method. Single-crystal structure is initiated at a seed surface, and made to extend across a dielectric surface by melting and resolidifying.Melting is effected upon irradiation with optical radiation which is focused onto an elongated zone; the zone is moved so as to locally melt successive portions of a layer of precursor material which may be amorphous or polycrystalline. The use of incoherent radiation is convenient, and focusing is typically by using a reflector.The process is conveniently effected under a controlled atmosphere and the layer being crystallized may be encapsulated so that no free semiconductor surface is exposed to an atmosphere.

    Abstract: A polycrystalline semiconductor sheet may be converted to a monocrystalline or macrocrystalline semiconductor sheet through use of a geometric restriction in the sheet. The process requires formation of a region of the sheet having a small width compared to the width of the remainder of the sheet. A molten zone is formed in the small width region of the sheet. At least a portion of the molten zone is allowed to solidify into a single crystal or crystals of large size of the semiconductor material coextensive with the small width of the region at the portion of the molten zone so solidified. The molten zone is then moved from the small width region of the sheet into the remainder of the sheet. The sheet is allowed to solidify successively as the molten zone passes along it. As a result, the macrocrystal formed in the narrow width region of the sheet propagates into the remainder of the sheet through which the molten zone passes. This process allows formation of high modified semiconductor material without requiring use of a seed crystal.
