NOVELTY - The device comprises a crucible (12) for containing a molten crystalline material (14), a support (16) for accommodating a seed on an end of the support and for moving along a translation axis in a pull direction to draw a seed crystal (24) from the crystalline material for initiating growth of a crystalline body (26) along a growth path, nozzles (22) positioned relative to the growth path and configured to provide the fluid to the crystal body effective to shape the crystal body as the crystalline material is pulled in the pull direction along the growth path, and a heating element.    USE - The device is useful for forming crystalline bodies from molten crystalline material, a seed and a fluid, where the crystalline bodies are useful as finished products such as a substrate material for microelectronic devices such as a solar cell and integrated circuit.    ADVANTAGE - The device is capable of economically forming the thin-sheet crystalline bodies with desired size and shape and high performance and without any material wastage, and eliminates or reduces the need for tiling and wiring of substrates.    DETAILED DESCRIPTION - The device comprises a crucible (12) for containing a molten crystalline material (14), a support (16) for accommodating a seed on an end of the support and for moving along a translation axis in a pull direction to draw a seed crystal (24) from the crystalline material for initiating growth of a crystalline body (26) along a growth path, nozzles (22) positioned relative to the growth path and configured to provide the fluid to the crystal body effective to shape the crystal body as the crystalline material is pulled in the pull direction along the growth path, and a heating element. The crystalline body includes a molten portion and a solid portion. The nozzles are positioned relative to the crystalline body such that fluid discharged from the nozzles impinges upon the molten portion, are configured such that the fluid discharged from the nozzles flows in a direction generally opposite to the pull direction, comprise a body defining discharge openings, which are elongated and are configured such that the discharge openings are linear openings arranged for forming the crystalline body into a flat sheet, and are arranged as pairs of nozzles. The support comprises an elongated cross-section. The fluid discharged from the nozzles comprises an inert gas. The heating element is configured to heat the fluid discharged from the nozzles to the melting point of the crystalline material. A nozzle from respective pair of nozzles is positioned opposite to the other nozzle from the respective pair of nozzles relative to the translation axis. INDEPENDENT CLAIMS are included for:    (1) a method of manufacturing crystalline bodies and devices from crystalline bodies using a seed crystal, a molten crystalline material and a fluid; and    (2) a computer-controlled system for forming crystalline bodies from molten crystalline material, a seed, and a fluid.
