Patent ID: 7744730

Claim:
A processing system comprising: a sputtering system comprising: a low pressure chamber; a rotatable first pallet in the chamber, the rotatable first pallet having a plurality of workpiece support areas for concurrently supporting a plurality of workpieces on the first pallet; a plurality of targets having sputtering surfaces facing the first pallet, the targets being located in a first plane, each of the targets having a substantially triangular shape; a first port for receiving workpieces one at a time for loading one at a time onto the workpiece support areas; a first motor for rotating the first pallet such that workpieces oppose different target sputtering surfaces at different times during sputtering operations; a plurality of magnets, each magnet opposing a back side of an associated target, the magnets being located in a second plane, each of the magnets having a substantially triangular shape; and an actuator connected to the magnets for identically scanning the magnets back and forth in a curved path in only the second plane over their associated targets during a sputtering operation, the curved path being less than 90 degrees, such that after a plurality of scans of the magnets each magnet scans a substantially triangular area corresponding to a shape of its associated target.
