  • Method for manufacturing a silicon cylinder by growth on seeds in a directed solidification furnace
    Patent number: 10125430
    Abstract: A method for manufacturing a silicon cylinder by growth on seeds in a directed solidification furnace, including at least the following steps: (i) providing a crucible having a longitudinal axis (Z), in which the bottom is covered with a layer of seeds of monocrystalline silicon in a right prism shape; and (ii) proceeding with directed solidification of silicon by growth on seeds, in a direction of growth that is co-linear with the axis (Z) and with a concave solidification front, spatially or temporally; characterized in that the layer in step (i) of: one or more central seeds Gc; and one or more peripheral seeds Gp contiguous to the seed(s) Gc, the peripheral seeds Gp having a specific size.

  • Device for producing a block of crystalline material with modulation of the thermal conductivity
    Patent number: 8172944
    Abstract: The device for producing a block of crystalline material from a bath of molten material comprises a crucible having a bottom and heat extraction means arranged under the crucible. It also comprises means for modulating the thermal conductivity fitted between the bottom of the crucible and the heat extraction means. The means for modulating the thermal conductivity comprise a plurality of plates made from thermally conducting material of low emissivity, parallel to the bottom of the crucible, and means for moving said plates closer to and away from one another.
