METHOD AND APPARATUS FOR GROWING SHAPED CRYSTALS

摘要

A high temperature heat exchanger (20) is used with the Czochralski crystal growing method to control the heat extraction from crystal silicon ingots (12) as they are grown. The high temperature heat exchanger (20) also acts as a shaping die (20) so that silicon bars, or ingots (12) of various shapes, including square, circular, rectangular or ribbon, can be produced by shaping during the growth stage.
