    Abstract: An apparatus for producing monocrystals having a relatively large cross-section by the Verneuil technique wherein a seed crystal is mounted on a movable crystal support member within a furnace means having a burner guiding flame gases and crystal growth material for impingement against the seed crystal so that the material melts and adheres to the seed crystal and forms a monocrystal which grows axially upwardly therefrom while the seed crystal member is moved axially downwardly a distance corresponding to the amount of axial crystal growth so that substantially uniform growth conditions are maintained throughout the growing process. A relatively massive flame deflector member having a central passage therein is positioned within a furnace means in spaced registry from the burner and radially about the crystal support member so as to deflect the flame gases laterally away from the growing crystal and to receive sufficient heat therefrom to form a heat reservoir for the growing crystal after flame shutdown. At least one axially movable insert member is positioned within the through passage of the deflector member and radially spaced from the crystal support member and the deflector member so as to be selectively movable in relation to the deflector member and the support member.

    Abstract: A flame fusion process for the production of synthetic monocrystalline bodies which comprises horizontally supporting a monocrystalline rod at each end of its axis within a furnace, the rod having at least one radially enlarged portion thereon, passing powdered material of the same composition as the rod through a flame to fuse the same, directing the flame at the outer periphery of the radially enlarged portion of the rod thereby depositing and building up the fused material by crystallization on such outer periphery, rotating the rod about its axis at a rate fast enough so that the part of the outer periphery of the radially enlarged portion of the rod which is in contact with the flame is in the molten state thereby resulting in a radially outwardly enlarging crystal of increasing diameter and varying the distance between the flame and the outer periphery of the radially enlarged portion of the rod as the diameter of the crystal increases to maintain a predetermined relationship between the flame and such outer periphery.

    Abstract: This invention is directed toward a method and apparatus for producing fracture-free crystalline boules through a simultaneous growing and annealing technique. It involves a conventional flame-fusion crystal-growing process and apparatus modified to effect crystal growth by using a high temperature fusion flame within a controlled heated zone. The temperature of the zone is controlled in the top portion at a temperature sufficient to effect crystal growth and in the bottom portion at a temperature sufficient to effect a complete anneal of the grown crystal. The device of this invention comprises a conventional Verneuil type crystal growing apparatus modified by the addition of a high temperature furnace arranged concentrically around the growing chamber. The growing chamber comprises an elongated tube of high temperature resistant material, such as zirconia, positioned and aligned directly below a powder dispensing assembly and burner assembly. The growing chamber passes through the center of the furnace which includes a high temperature tungsten mesh heating element, heat shields and a water-jacketed cover.

    Abstract: A method and apparatus for manufacturing semiconductor bodies from germanium-silicon or molybdenum-silicon in which a homogeneous melt of the substance under treatment is made in a melting vessel which has a capillary opening in the bottom. A vertically movable receiver, such as a crucible, is mounted beneath the capillary opening, and a piston is movable up and down in the melting vessel above said capillary opening to press drops of the molten substance in said vessel out through said opening and into the receiver where said substance is solidified in crystalline form. The method and apparatus insure that the dropping sequence of said drops causes each consecutive drop to enter the receiver before the preceding drop has fully solidified.
