The tubed silicon crystalline it is produced with tubed silicon crystalline production manner and its production manner

摘要

Topic It offers the tubed silicon crystalline makes that it produces the tubed silicon crystalline from silicon raw materials without doing cutting work possible, produces with tubed silicon crystalline production manner and that production manner. SolutionsCoefficient of thermal expansion is smaller than silicon, coefficient of thermal expansion is larger than the molten liquid storage container and the silicon which were formed with the material whose melting point is high, the core which was formed with the material whose melting point is high is used. Nitriding silicon (Si₃ N₄) it applies to the inside of the aforementioned molten liquid storage container, and the outside of aforementioned core lays out aforementioned core inside the aforementioned molten liquid storage container. And, restoration the silicon molten liquid in the void which at the inside of the aforementioned molten liquid storage container and the outside of aforementioned core was formed, while maintaining the liquid Characteristic of the aforementioned silicon molten liquid, from base side of the aforementioned molten liquid storage container it provides temperature gradient to above, makes the aforementioned silicon molten liquid solidify.
