Abstract: A system for growing a crystal ingot from a melt includes a first crucible, a second crucible, and a weir. The first crucible has a first base with a top surface and a first sidewall that form a first cavity. The second crucible is disposed within the first cavity of the first crucible, and has a second base and a second sidewall that form a second cavity. The second base has a bottom surface that is shaped to allow the second base to rest against the top surface of the first base. The second crucible includes a crucible passageway to allow movement of the melt therethrough. The weir is disposed inward from the second sidewall to inhibit movement of the melt from a location outward of the weir to a location inward of the weir.

Abstract: A crystal puller for growing a crystal ingot includes a housing, insulation, a crucible assembly, a heat shield, and a dust barrier. The housing encloses a growth chamber, and has an upper wall with an inner surface and an aperture. The insulation separates an inside of the housing into an upper area and a lower area, and has a central opening. The crucible assembly is within the lower area to contain the melt. The heat shield is adjacent the central opening of the insulation, and forms a labyrinth gas path with the crucible assembly. The dust barrier extends from the inner surface of the upper wall to one of the insulation and the heat shield, and forms a seal with the upper wall around the aperture to inhibit particles from entering the growth chamber through the upper area of the housing.

Abstract: A dopant funnel for loading dopant pellets into a dispenser tube of a dopant dispenser is disclosed. The dopant funnel has a cup connected through a restrictor to a shaft. The cup holds randomly oriented dopant pellets. The restrictor meters the amount and orientation of dopant pellets being removed from the cup. The shaft is in alignment with the restrictor for delivering dopant pellets from the cup to the dispenser tube.
