  • Publication number: 20090115059
    Abstract: A gold wire for semiconductor element connection having high strength and bondability. The connection has a limited amount of at least one element selected from calcium and rare earth elements, and a limited amount of at least one element selected from a group consisting of titanium, vanadium, chromium, hafnium, niobium, tungsten, and zirconium. The incorporation of a suitable amount of palladium or beryllium is preferred. The incorporation of calcium and rare earth element can improve the strength and young's modulus of a gold wire, and the incorporation of titanium and the like can reduce a deterioration in the roundness of press-bonded shape of press-bonded balls in the first bonding caused by the incorporation of calcium and rare earth elements. The bonding wire can simultaneously realize mechanical properties and bondability capable of meeting a demand for a size reduction in semiconductor and a reduction in electrode pad pitch.
