Abstract
To reduce pumping time of a vacuum treatment chamber served by a transport arrangement in a transport chamber. The vacuum treatment chamber is split in a workpiece treatment compartment and in a pumping compartment in mutual free flow communication and arranged opposite each other with respect to a movement path of the transport arrangement serving the vacuum treatment chamber. The pumping compartment allows providing a pumping port of a flow cross-section area freely selectable independently from the geometry of the treatment compartment.
