Abstract
A crystal-growing machine (10) includes a furnace chamber (12) and two loading chambers (14 and 16) that permit simultaneous processing operations. At least one of the two loading chambers (14 and 16) includes a lifting mechanism (36) for pulling a crystal (40) from a melt (20) in the furnace chamber (12). A positioning mechanism (60) disengages one of the loading chambers (14 and 16) from the furnace chamber (12) for cooling the crystal (40) in an evacuated environment and engages the other of the loading chambers (14 and 16) for simultaneously recharging the melt (20) or starting growth of another crystal.
