DUAL PURPOSE FLOATING ZONE AND

CRYSTAL PULLING FIXTURE A new fixture with separate attachments for crystal pulling and floating zone appli­cations for use with a high frequency induction heating generator.

THE FLOATING ZONE METHOD is used ex­tensively for zone refining and for grow­ing crystals of high purity silicon for semi­conductor devices by traversing a narrow molten zone along the length of the proc­ess bar in a controlled atmosphere.

THE CRYSTAL PULLING METHOD is used for growing single crystals of various mate­rials, especially germanium, by bringing a seed of known crystal orientation into contact with the surface of the molten metai and slowly withdrawing the seed, producing progressive crystallization.

The Lepel Model HCP-D consists of the basic unit with the traverse mechanism and all the controls including the controls for the operation of the generator, and the floating zone and crystal pulling attach­ments. The same basic support, program­ming and control unit is used in either adaptation. The major variations are in the attachments and the induction coils. The

change from one application to the other can be accomplished in

a very short time.
