Patent ID: 7347919

Claim:
A sputter source including a plurality of targets sputtered at a time for providing a film on a substrate, the sputter source comprising: a plurality of elongate anode electrodes disposed on a surface of a target attachment plate; cathode electrodes each disposed between the anode electrodes, wherein each of the targets is disposed on one of the cathode electrodes; and magnetic field forming devices disposed at the rear surface side of the target attachment plate at immediate back of the targets, respectively, wherein the anode electrodes and the targets are fixed to the target attachment plate, and the respective magnetic field forming devices and the target attachment plate are capable of moving relatively to each other and the target attachment plate is capable of moving relative to the substrate, wherein the magnetic field forming devices move parallel to the targets, and wherein the magnetic field forming device is moved in a range between the anode electrodes in such a manner that the magnetic field forming device is not located at immediate back of the anode electrode.
