Patent ID: 8663388

Claim:
A method for manufacturing a conductive single crystal wire, comprising the steps of: placing in a growth crucible at least one metal selected from the group consisting of gold, copper, silver, aluminum and nickel; heating and melting the metal placed in the growth crucible; growing a single crystal using metal crystal as a seed by Czochralski or Bridgman method; cutting the grown single crystal by electric discharge machining into a plurality of single crystal discs having a predetermined thickness of an intended wire; and producing by electric discharge machining each of the cut single crystal discs into an elongated single crystal wire, wherein said electric discharge machining is performed either by cutting the single crystal disc in an inward spiral pattern from an outer surface into a center axis of the single crystal disc to produce the elongated single crystal wire with the predetermined thickness, or by firstly forming an axial central hole in a central axis of the single crystal disc, then cutting the single crystal disc in an outward spiral pattern from the axial central hole to the outer surface of the single crystal disc to produce the elongated single crystal wire with the predetermined thickness.
