Single crystal drawing up apparatus
专利汇可以提供Single crystal drawing up apparatus专利检索，专利查询，专利分析的服务。并且PURPOSE: To equalize a dopant concn. as well as a temp. within a molten liquid and make it possible to prepare a high quality single crystal by a method wherein, in a crusible fixed type single crystal drawing up apparatus, a molten liquid rotating system forming a rotary magnetic field is provided.
CONSTITUTION: To a lower portion of a crusible 1 of a single crystal drawing up apparatus, is provided a molten liquid rotating system 8 comprising a doughnut like electric conductor 10 forming a rotary magnetic field. In case of drawing up a single crystal, a drawing up shaft 3 of which a chuck portion 4 is attached by seed crystal 5 is lowered to immerse a lower end of a seed crystal 5 into a molten liquid 6 of a crusible 1 and, thereafter, a drawing up shaft 3 is raised while rotated to grow a single crystal 7 onto a lower end of a seed crystal 5. In this case, because a molten liquid 6 is rotated in a predetermined speed by a molten liquid rotating system 8, a molten liquid 6 is totally mixed sufficiently and the temp. as well as an impurity concn. are equalized.
