Zones melting device with an improved susceptor and method for floating zone melting

摘要

Zones melting device for the crucible-free zone melting of a silicon element (4) an irregular structure, comprising a hf - induction heating coil (7), a element retainers (2) and a crystal nucleus holder (5), the vertical alignment above and below the hf - induction heating coil (7) are arranged,the element retainers (2) is designed in such a way that it includes an end of the silicon member (4) holds an irregular shape, and the crystal nucleus holder (5) is designed in such a way that it holds a crystal nucleus of silicon,a device (3), with which the element retainers (2) with respect to the hf - induction heating coil (7) is adapted to be positioned such that the free end of the silicon member (4) an irregular shape in the vicinity of the hf - induction heating coil (7) is adapted to be brought, with the formation of a molten zone melting,a device (6), with which the crystal nucleus holder (5) with respect to the hf - induction heating coil (7) is adapted to be positioned such that the crystal nucleus with the molten zone comes into contact and melts,a device (8) for varying the relative arrangement of the hf - induction heating coil (7) to the silicon element..
