Abstract: Methods for removing a melt of silicon from a crucible used in a silicon ingot growth process and associated wick assemblies are disclosed. The wick is made of porous carbon that ignites upon reaching an ignition temperature causing relatively rapid and relatively large volume take-up of silicon from the crucible.

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.
