ABSTRACT:
An induction heating coil for the float zone melting of semiconductor materials. The distribution of current on the surfaces of the coil is modified by altering the surfaces of the coil. The alteration of the surfaces is in the form of selectively positioned saw slots and solid conductor strips. The current distribution can be controlled independently on the top and bottom surfaces of the coil.
