Abstract
Methods for growing a reduced dislocation crystal ingot in an ingot growing system are disclosed. The system has a first crucible with a first base and a first sidewall extending upward from the first base to define an outer cavity. The method includes placing a weir in the outer cavity, placing a second crucible on the weir, placing feedstock material into the outer cavity, and melting the feedstock material to allow movement of the melt from the outer cavity inward of an intermediate cavity and into an inner cavity.
