Abstract
The sputtering system of the present invention includes a spare collimator storage chamber for accommodating one or more spare collimators and a processing chamber, which are provided in one-piece or in communication with each other through a gate valve. A used collimator in the processing chamber is quickly and readily replaced with a new collimator stored in the spare collimator storage chamber by a collimator exchanging device without exposing the interior of the processing chamber to atmospheric air.
