Abstract
A system for growing a crystal ingot from a melt is provided. The system includes a first crucible, a barrier, and a shield. The first crucible has a first base and a first sidewall forming a first cavity for containing the melt. The barrier is disposed within the first cavity of the first crucible to inhibit movement of the melt from outward of the barrier to inward of the barrier. The barrier extends from the first base to above the melt. The barrier has an inner arm and an outer arm extending upward to form a channel therebetween. The shield extends downward between the inner arm and the outer arm to inhibit passage of contaminants.

A system for growing a crystal ingot from a melt, the system comprising:
- a first crucible having a first base and a first sidewall forming a first cavity for containing the melt;
- a barrier disposed within the first cavity of the first crucible to inhibit movement of the melt from outward of the barrier to inward of the barrier, the barrier extending from the first base to above the melt to be contained therein, the barrier having an inner arm and an outer arm extending upward to form a channel therebetween;
- and
- a shield extending downward between the inner arm and the outer arm to inhibit passage of contaminants.
A system for growing a crystal ingot from a melt, the system comprising:
- a first crucible having a first base and a first sidewall forming a first cavity for containing the melt;
- a barrier disposed within the first cavity of the first crucible to inhibit movement of the melt from a location outward of the barrier to a location inward of the barrier;
- a divider disposed on top of the barrier, the divider having an upwardly extending inner arm and an upwardly extending outer arm;
- and
- a shield extending downward between the inner arm and the outer arm to inhibit passage of contaminants.
