Abstract:
1. A method for manufacturing a coated circular substrate, comprising (a) providing a circular area with a radius in a sputtering chamber (b) introducing into said sputtering chamber one substrate of said radius or more than one substrate defining in combination an area of said radius; (c) rotating said at least one substrate about a first central axis of said circular area; (d) providing a single magnetron sputtering source with a circular sputtering surface and having a second central axis oblique with respect to and intersecting said first central axis; (e) selecting the diameter of said circular area to be larger than the diameter of said circular sputtering surface; (f) selecting an intersection angle of said first and second central axis to be: (g) magnetron sputter coating said at least one substrate by said single magnetron sputtering source.
