  • Patent number: 10273573
    Abstract: A method of depositing coating onto both sides of a substrate is provided, which includes steps of upwardly sputtering one or more lower targets to deposit a sacrificial coating onto a second surface and downwardly sputtering one or more upper targets to deposit a first functional coating onto a first surface, washing the substrate with one or more washers to remove the sacrificial coating from the second surface while leaving intact the first functional coating on the first surface, and downwardly sputtering the one or more upper targets to deposit a second functional coating onto the second surface.
