  • Process for producing a tube-shaped cathode sputtering target
    Patent number: 6719034
    Abstract: A process for producing a tube target for cathode sputtering plants, in which the tube target is formed from a metallic inner tube (target holder) made of a first material with a first melting point of Ts1≧900 K and a metallic outer tube (target) that concentrically surrounds the inner tube and that is made of a second material with a second melting point of Ts2≦800 K. The inside diameter of the outer tube and the outside diameter of the inner tube are proportioned in such a way that the two tubes fit together tightly and are mechanically firmly joined. The outer tube is formed by casting the second material in a molten state in a heated, vertical, cylindrical permanent mold, which has a heated mandrel that constitutes the inner tube.
