Patent ID: 7090754

Claim:
A sputtering device comprising: a vacuum chamber; a substrate holder for holding a substrate within said vacuum chamber; a substrate holder rotating device for rotating said substrate holder and the substrate to be held by said substrate holder; a plurality of sputtering cathode units, each of said sputtering cathode units including a plurality of sputtering cathodes, each of said sputtering cathodes having a target arranged to face the substrate to be held by said substrate holder so that said target is sputtered to form a film on the substrate; a driving mechanism for moving said sputtering cathode units along an arcuate path across a surface of the substrate to be held by said substrate holder; and a sputtering system for sputtering at least one target as at least one of said sputtering cathode units moves across the substrate held by said substrate holder rotated by said substrate holder rotating device, said sputtering system being operable to independently adjust electric power to be supplied to each of said sputtering cathodes of each of said sputtering cathode units.
