Abstract
A sputtering installation has two longitudinally extended magnetrons disposed next to one another and each has a target on an upper side thereof. Increasing utilization of the targets in the sputtering installation is accomplished by homogenizing the discharge resistance of the magnetrons along the directrix such that a partial discharge resistance of a target point on the directrix has the same magnitude as the partial discharge resistance of a different target point on the directrix.
