ABSTRACT:
Several embodiments of a replenishment arrangement for furnishing molten semiconductor material to furnaces for growing monocrystalline boules are described. A replenishment crucible within which a melt of the material from which the boules are to be grown is communicated either intermittently or continuously with a plurality of growth furnaces. The melt level in all of the growth crucibles is controlled by determining the level of molten material in the replenishment crucible.
