Abstract: A method and system for double-layer continuous Cz crystal growing are disclosed. The system includes a crucible assembly including an inner crucible in an outer crucible, the inner crucible defining a growth region and a feed region, the crucible assembly containing molten material (e.g., silicon). The system also includes a susceptor, a continuous feed supply for providing a continuous feed to the feed region, and a temperature control system disposed about the susceptor and configured to cool a region of silicon at a bottom of the growth region to form a solid layer, the solid layer facilitating reducing an oxygen concentration in the growing crystal. The method includes separating molten material into the growth region and the feed region, initiating cooling at a bottom of the growth region, and solidifying a region of material at the bottom of the growth region, such that a solid layer is formed.

Abstract: A system for extracting liquid is provided. The system includes a vacuum source and a nozzle having a wettable plunger and a vacuum tube connected in flow communication with the vacuum source. When the plunger is partly submerged in the liquid and the vacuum source is actuated to initiate a flow of gas through the vacuum tube, droplets of the liquid separate from at least a portion of the unsubmerged part of the plunger and become suspended in the gas flow. The system also includes a cooling structure positioned adjacent to the vacuum tube to facilitate solidifying the droplets suspended in the gas flowing through the vacuum tube.
