A cathode assembly for a sputter deposition apparatus and a method for coating a substrate is provided. The cathode assembly has a coating side for coating on a substrate. Further, the cathode assembly includes a rotary target assembly adapted for rotating a target material around a rotary axis; at least a first magnet having an inner magnet pole and at least one outer magnet poles and being adapted for generating one or more plasma regions. The cathode assembly has a first angular coordinate for a magnet pole, the magnet pole being provided for the coating side, and a second angular coordinate for a further magnet pole, the magnet pole being provided for the coating side; wherein the first angular coordinate and the second angular coordinate define an angle a larger than about 20 degrees and smaller than about 160 degrees.
