Abstract:
1. A method for producing a coated substrate, the method comprising: providing a first precursor, a second precursor and a substrate, the first precursor being a copper complex that contains no fluorine and the second precursor being selected from a ruthenium complex, a nickel complex, a palladium complex, and mixtures thereof; depositing a layer using atomic layer deposition (ALD) at least on partial regions of a surface of the substrate by using the first precursor and the second precursor, the layer containing copper and at least one of ruthenium, nickel and palladium, wherein a molar ratio of the first precursor of at least 90% and a molar ratio of the second precursor of not more than 2% is used; wherein the atomic layer deposition includes a pulse, in which the first and the second precursor are evaporated, and in which the substrate is exposed to a precursor mixture of the first precursor and the second precursor; and wherein during said pulse, the first precursor and the second precursor are either: used as a mixture of the first and the second precursor, the mixture being evaporated from exactly one evaporation unit, or simultaneously evaporated from a first evaporation unit and a second evaporation unit, wherein the evaporation of the second precursor from the second evaporation unit starts at least milliseconds before the evaporation of the first precursor from the first evaporation unit; and wherein the second precursor, oxidized metal obtained from the second precursor during the ALD and/or elemental metal obtained from the second precursor during the ALD, respectively, act either
