Abstract:
A high throughput sputtering apparatus for providing a single or multi-layer coating to the surface of a plurality of substrates, said apparatus comprising:a plurality of buffer and sputtering chambers, said sputtering chambers including:a plurality of planar cathodes, each with first and second surfaces, wherein the cathodes are mounted within said sputtering chambers in a plane oriented substantially parallel to a plane including the plurality of substrates,a plurality of targets positioned on the first surfaces to provide sources for films to be sputtered,magnet means for generating magnetic flux lines over the first surfaces and the targets, which lines are sufficient to support sputtering and form substantially horizontal flux paths parallel to the first surfaces and the targets, anda shield for shielding the substrates from obliquely incident deposition from the targets, the shield including flanges extending from the cathodes and projecting toward the substrates.
