Patent ID: 7479210

Claim:
A sputtering system comprising: a sub-atmospheric pressure chamber; a pallet in the chamber, the pallet having a plurality of workpiece support areas for concurrently supporting a plurality of workpieces on the pallet; a target support surface for supporting a plurality of targets having sputtering surfaces facing the pallet; a rotating table supporting the pallet, the pallet having a bottom surface in thermal and electrical contact with the table; a conduit in thermal contact with the table to control a temperature of the workpieces supported on the pallet, the conduit for having a temperature controlling liquid flowing through it; and a motor for rotating the pallet such that workpieces oppose different target sputtering surfaces at different times during sputtering operations, wherein the conduit comprises a thermally conductive pipe that contacts the table, the pipe rotating with the table, wherein the pallet is secured to the table with screws, wherein screw holes for the screws are located in the workpiece support areas so that sputtered material will be blocked by the workpieces and not be deposited on the screws.
