A WIRE FOR SEMICONDUCTOR AND A MANUFACTURING METHOD THEREOF

摘要

The present invention relates to a method of manufacturing wires used for solid-state devices. This manufacturing process positions a silver rod vertically at the center of a mold, inserts the mold containing the silver rod into an electrical furnace, heats the mold until the surface of the rod becomes in half-melted or pre-heated state, injects melted gold into the mold to wrap the silver rod, cooling slowly the silver rod in the electrical furnace until the melted gold infiltrates into the silver rod, anneals the silver rod in an annealing furnace, and stretches the annealed silver rod to necessary diameter after extracting from the mold.
