Patent ID: 7993456

Claim:
A device for carrying out a surface treatment of a substrate under vacuum, comprising: a housing including at least two chambers communicating with at least one vacuum source, at least one of the chambers being designed to serve as a vacuum lock chamber which can be opened to atmosphere and in which the substrate can be introduced and removed to access the remaining chambers, wherein the housing includes an upper housing half and a lower housing half peripherally joined by a flexible sealing member, at least one of the housing halves having at least two symmetrically distributed recesses, which are intended to constitute at least some of the chambers, together with a revolver pivotally mounted between the housing halves and including revolver recesses in which the substrate is intended to be placed, wherein outer walls of the upper and lower housing halves under an action of a force-generating member are designed to be moved from a first position in which the upper and lower housing halves, through tight, sealing contact with the revolver, prevent rotation thereof, to a second position in which the upper and lower housing halves are separated from the revolver in order to permit rotation of the latter to predefined positions, and wherein at least one of the revolver recesses at least partially coincides with one of the chambers, allowing the substrate to be moved between the chambers.
