Abstract:
1. A sputtering system comprising: a sputtering chamber, a substrate and a sputtering material layer that is to be sputtered wherein the substrate and the sputtering material layer are located within the sputtering chamber; the sputtering material layer having a sputtering surface where atoms of the sputtering material are to be sputtered and the substrate having a forming surface with a site where a sputtered layer is to be formed by said sputtering; the sputtering material layer having a sputtering center which is located at a center of atoms to be sputtered from the sputtering material layer; an ion beam gun located within the sputtering chamber and positioned therein to direct a center of an ion beam at said sputtering center for causing sputtering from the sputtering material layer along a central axis which is centered within the sputtering; said site having a periphery with a site center located at a center of said periphery; and the central axis of the sputtering being offset from said site center wherein the offset extends within a plane which is parallel to the sputtering surface in a direction which is normal to a plane defined by the center of the ion beam at the ion beam gun and said central axis.
