Abstract
A new design of directional solidification furnace is proposed to grow multi crystalline silicon. In the modified furnace, three holes with the same size were inserted on the graphite retort. The radiation heat transfer through the modified retort is considered. A 2-D axis symmetry model is applied in simulation. The temperature distribution, melt crystal interface, thermal stress, impurities (carbon and oxygen) and dislocation density were compared between conventional and modified models. The result shows that higher crystal quality can be obtained by the retort modification.
