Patent ID: 6841202

Claim:
A device for the plasma treatment of objects in a vacuum comprising; a box-shaped structure of an electrically conductive material defining a vacuum chamber to which a vacuum may be applied, a support for supporting and electrically insulating the objects from the surrounding box-shaped structure, said box-shaped structure having inner walls completely surrounding said support on all sides and including at least one opening that can be opened for ingress and egress of objects and closed whereby an object to be coated is moved through said opening and placed on said support out of direct contact with said inner walls of said box-shaped structure, said box-shaped structure including a working gas inlet for supplying a working gas and a working gas outlet for discharging the working gas, said box-shaped structure including an energy opening for introducing energy to create the plasma, all of said inner walls of said box-shaped structure having an electrical charge opposite to the charge of the plasma whereby all of said inner walls of the box-shaped structure act as an electrode completely surrounding the support whereby objects on the support are out of direct contact on all sides to the inner walls of the box-shaped structure, all of said inner walls of said box shaped structure presenting a coating material for removal from the structure and deposition on the objects.
