ABSTRACT:
A bundle of carbon fibers each coated with copper or copper alloy is uniformly wound around a core rod under tension, and subjected to a hot press treatment in a non-oxidizing atmosphere. The core rod is then cut off along the surface of a plate formed by the hot-press to form a supporting electrode plate for a semiconductor device. The electrode plate thus fabricated incorporates therein carbon fibers in a spiral and concentric circular array around the core rod.
