    摘要: A weighing system is provided for a continuous Czochralski process that accurately measures the weight of the crucible and melt during crystal growth to control the introduction of feedstock in order to keep the weight approximately constant. The system can measure the weight of the crucible while the crucible is rotating, and is insensitive to vibrations of the melt surface as well as variable torques on the crucible shaft induced by the rotation. The system also measures the weight of the crucible and its contents in order to control the amount of feedstock recharged after an ingot is withdrawn.

    摘要: A method is disclosed for continuous CZ crystal growing wherein one or more crystal ingots are pulled into a growth chamber from a crystal/melt interface defined in a crucible containing molten crystalline material that is continuously replenished by crystalline feedstock. The method includes separating the molten crystalline material, controlling the flow of the molten crystalline material and defining an annular space with respect to sidewalls of a heat shield in the chamber.
