ABSTRACT:
A breakapart single turn RF induction coil suitable for use in zone refining production of large diameter semiconductor rods is described wherein the coil is engagable and disengagable from mounted semiconductor rods without breaking the rod or mounting welds. The work coil consists of two spaced apart sections; however connected at one or both ends of a slit formed between the two sections with current and coolant flow through the connection means on the outer peripheral of the sections. The arrangement affords the use of a single turn coil having the capacity for removal from a float zone without disruption of the semiconductor rod mounting.
