Abstract:
Process for forming a coating on at least one substrate by cathodic sputtering comprisingtransfer of the at least one substrate between an inlet and an outlet of a cathodic sputtering chamber,passage of at least one surface to be coated of the substrate parallel to a surface of a target, oriented towards the substrate surface and containing one or more elements to be deposited on the substrate, andduring this passage, cathodic sputtering of said one or more elements to be deposited on the entirety of the surface to be coated from said target surface,characterized in that it comprisessurface coating of the at least one substrate transferred into the chamber by a target, said substrate having a maximum width and said surface of said target having an invariable length approximately matching said maximum width of the substrate, and,depending upon the width of the substrate being coated, relative displacement between the surface of the target and the surface to be coated of the substrate, such that substantially the entirety of the surface of the target is constantly located opposite the surface of said substrate to be coated during cathodic sputtering.
