ABSTRACT:
A crucible is formed of a cylindrical body member and a disk-shaped nozzle member fitted to the bottom portion of the body member, and the nozzle member is provided with a nozzle hole for discharging out a semiconductor molten solution dropwise therethrough. The semiconductor molten solution drops discharged out of the crucible through the nozzle hole are cooled and solidified during falling to become semiconductor grains. Silicon grains having high crystal quality can be manufactured at low cost.
