1. A device for depositing uniform layers on rotationally moved substrates by means of magnetron sputtering comprising
(a) a vacuum chamber with a sputtering compartment,
(b) at least one inlet for a sputtering gas;
(c) a turntable with at least one substrate holder; and
(d) at least one magnetron sputtering source arranged in the sputtering compartment with at least one electrode, and
at least one further microwave plasma source being arranged in the sputtering compartment; and
wherein the at least one microwave plasma source for local plasma compression is arranged asymmetrically to one of the axes of the at least one electrode, and wherein the at least one microwave plasma source is placed at an end of the at least one magnetron sputtering source.
