  • Patent number: 10658163
    Abstract: Provided is a tantalum target, wherein, when a direction normal to a rolling surface (ND), which is a cross section perpendicular to a sputtering surface of a target, is observed via an electron backscatter diffraction pattern method, an area ratio of crystal grains of which a {100} plane is oriented in the ND is 30% or more. An object of the present invention is to provide a tantalum sputtering target in which a deposition rate can be appropriately controlled under high-power sputtering conditions. When sputter-deposition is performed using this kind of a tantalum target, it is possible to form a thin film having superior film thickness uniformity and improve the productivity of the thin film formation process, even for micro wiring.

  • Patent number: 10557195
    Abstract: A sputtering target and/or a coil disposed at a periphery of a plasma-generating region for confining plasma are provided. The target and/or coil has a surface to be eroded having a hydrogen content of 500 ?L/cm2 or less. In dealing with reduction in hydrogen content of the surface of the target and/or coil, a process of producing the target and/or coil, in particular, conditions for heating the surface of the target and/or coil, which is believed to be a cause of hydrogen occlusion, are appropriately regulated. As a result, hydrogen occlusion at the surface of the target can be reduced, and the degree of vacuum during sputtering can be improved. Thus, a target and/or coil is provided that has a uniform and fine structure, makes plasma stable, and allows a film to be formed with excellent uniformity. A method of producing the target and/or the coil is also provided.
