In accordance with an embodiment of the present invention, apparatus for ion-assisted magnetron deposition takes a form that includes a magnetron, a deposition substrate displaced from the magnetron, and an ion source also displaced from the magnetron and located so that the ion beam from the ion source is directed at the deposition substrate. The ion source is operated without an electron-emitting cathode-neutralizer, the electron current for this function being provided by electrons from the magnetron. In one specific embodiment, the ion source is operated so that the potential of the deposition substrate is maintained close to that of a common ground for the magnetron and the ion source. In another embodiment, the ion source is of the Hall-current type and the discharge current of the ion source is approximately equal in magnitude to the current of the magnetron discharge.
