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.
Claims19
A system for growing a crystal ingot from a silicon melt, the system comprising:
- a crucible having a base and a sidewall for containing the silicon melt therein;
- and a weir located along the base of the crucible at a location inward from the sidewall, the weir having a body connected with at least a pair of legs disposed to inhibit movement of the silicon melt therebetween.
A method for growing a crystal ingot, the method comprising:
- providing a crucible with a weir, the weir having an inner leg and an outer leg forming a space therebetween;
- placing a feedstock material into the crucible at a location that is outward of the weir;
- melting the feedstock material to form a melt able to flow to a location that is inward of the weir;
- and
- causing the melt to cool to form a crystal ingot.
