Abstract
A system for growing a crystal ingot includes a crucible and a weir. The crucible has a base and a sidewall for the containment of a silicon melt therein. The weir is located along the base of the crucible inward from the sidewall of the crucible. The weir has a body connected with at least a pair of legs disposed to inhibit movement of the silicon melt therebetween.
