  • Patent number: 8974707
    Abstract: Planar or tubular sputtering targets made of a silver base alloy and at least one further alloy component selected from indium, tin, antimony, and bismuth accounting jointly for a weight fraction of 0.01 to 5.0% by weight are known. However, moving on to ever larger targets, spark discharges are evident and often lead to losses especially in the production of large and high-resolution displays having comparatively small pixels. For producing a sputtering target with a large surface area on the basis of a silver alloy of this type, which has a surface area of more than 0.3 m2 as a planar sputtering target and has a length of at least 1.0 m as a tubular sputtering target, and in which the danger of spark discharges is reduced and thus a sputtering process with comparatively high power density is made feasible, the invention proposes that the silver base alloy has a crystalline structure with a mean grain size of less than 120 ?m, an oxygen content of less than 50 wt.

  • Patent number: 5480532
    Abstract: A target for production of transparent electrically conductive layers by cathode sputtering is produced from indium oxide-tin oxide powder mixtures or coprecipitated indium oxide-tin oxide powders. A target with especially high mechanical strength consists of an oxide ceramic material into which metallic phase components have been incorporated in a uniform and finely distributed manner and which has a density of more than 96% of the theoretical density of indium oxide/tin oxide consisting purely of oxide.

  • Patent number: 5480531
    Abstract: Oxide-ceramic targets of partially reduced indium oxide-tin oxide mixtures are described. The targets provide high sputter performances, and they exhibit an essentially defined degree of reduction between 0.02 and 0.3, a density between 75 and 98% of the theoretical density and a specific electric resistance between 89.times.10.sup.-3 and 0.25.times.10.sup.-3 .OMEGA. cm. The degree of reduction must not deviate at any point on the target surface by more than 5% from the average degree of reduction of the target. The targets are produced by means of hot-pressing the oxide mixtures which were partially reduced beforehand in a special method step.

  • Patent number: 5407548
    Abstract: The invention concerns a process for coating a substrate 1 of little or no corrosion resistance, especially a metal substrate having an alloy consisting at least of Ni, Cr and Fe, in an evacuable coating chamber 15, 15a. It comprises making an electrode that can be connected to a current supply 10, this electrode being electrically connected to a target 3 which is sputtered and the sputtered particles of which are deposited on the substrate 1. Reactive process gases are, for this purpose, supplied to the coating chamber 15, 15a, so that an amorphously depositing layer 2 is applied onto the substrate.
