  • Publication number: 20020083571
    Abstract: A method for producing metal sputtering target, comprising a step of double V melting process, and a step of high temperature forging. The step of double V melting process produces a single metal of aluminum, titanium, or copper, or an alloy of the single metal associated with at least a different metal selecting from one of copper, silicon, titanium, zirconium, osmium, molybdenum, tungsten, platinum, gold, niobium, tantalum, cobalt, rhenium, and scandium. The step of high temperature forging treats the single metal or the alloy to form the metal sputtering target material with small crystal grains and a secondary phase of fineness and high homogeneity suitable for using in semiconductor and photoelectric industries.
