ABSTRACT:
A new EFG (Edge-defined Film-fed Growth) crucible/die configuration is provided which (a) overcomes the tendency for silicon feed material to form a solid mass near the center hub region in the hot-zone during the crystal growth and (b) prevent the crucible/die unit from fracturing its supporting susceptor during cool-down.
