Claim 0:
1. A magnetron sputtering system comprising, in combination:
a vacuum chamber;
a substrate mount for mounting a substrate within the vacuum chamber;
a plurality of cathode assemblies including a first set of one or more cathode assemblies and a second set of one or more cathode assemblies, and configured for sputtering, each cathode assembly comprising:
a target comprising sputterable material and having an at least partially exposed planar sputtering surface, the target of the first set of one or more cathode assemblies being formed of a first material and the target of the second set of one or more cathode assemblies being formed of a second material different than the first material;
a target support configured to support the target in the vacuum chamber and rotate the target relative to the vacuum chamber about a target axis; and
a magnetic field source including a magnet array mounted to be substantially stationary relative to the vacuum chamber during sputtering, the target being positioned between the magnet array and the substrate mount; and

a cathode assemblies controller assembly operative to actuate the first set of cathode assemblies for sputtering the sputterable material of the first set of cathode assemblies without actuating the second set of cathode assemblies, and to actuate the second set of cathode assemblies for sputtering the sputterable material of the second set of cathode assemblies without actuating the first set of cathode assemblies.
