Method of and apparatus for growing crystal ribbon |
摘要 |
A method and apparatus for growing crystal ribbon from a liquid melt by the EFG technique includes the use of a die having a capillary feed passage adjacent the ribbon pulling mechanism and gas scrubbing passages on each side of the capillary feed passage. Thus, gas entrapped in the liquid melt can diffuse through the gas scrubbing passages to minimize the presence of microvoids in the ribbon. In a particular embodiment, the capillary die can include lateral communicating passages between the capillary feed passage and the gas scrubbing passage so that gas in the capillary feed passage can diffuse out to the gas scrubbing passage.
