Patent ID: 7943016

Claim:
Magnetron sputtering ( 2 ) arrangement comprising a target arrangement ( 3 ) comprising a target ( 3 ai) having a sputtering surface ( 4 ) the shape of which defines a first (A 1 ) and a second axis (A 2 ) being mutually perpendicular and being, at least approximately, axes of mirror-symmetry of the sputtering surface; a magnet arrangement ( 40 ) generating a magnetron magnetic field above said sputtering surface ( 4 ); and a drive ( 70 ) operatively connected to at least one of the magnet arrangement and the target arrangement for establishing a substantially transitional relative movement between said magnetron magnetic field and said sputtering surface ( 4 ); said relative movement describing a path ( 80 ) defining a third (A 3 ) and a fourth axis (A 4 ) being mutually perpendicular and being, at least approximately, axes of mirror-symmetry of the path, said third axis (A 3 ) being at least approximately parallel to said first axis, and said path ( 80 ) having at least two pointed corners ( 81 ), each corner located at least substantially on one of said third axis (A 3 ) and said fourth axis (A 4 ).
