Abstract
PURPOSE: To obtain the titled ingot having excellent characteristics and low defect content at a low cost, by putting silicon into a crucible, heating and melting the silicon with a heater in a heating chamber in an inert gas, slowly lowering the crucible from the heating zone without rotating the crucible and crystallizing the molten liquid.
CONSTITUTION: A crucible 5 containing silicon is placed in a heating chamber 1 and heated with a heater 6 in an inert gas atmosphere to melt the silicon in the crucible 5. the crucible 5 is slowly separated from the heating zone of the heater 6 by lowering the crucible 5 without rotating the crucible and the molten silicon is crystallized to obtain a silicon ingot. The growing direction of the crystal and the particle size of the crystal grains can be uniformized by the proper control of the cooling rate and the temperature distribution of the molten liquid. The silicon ingot produced by this process is suitable as a substrate for solar cell, etc.
