• a partition wall extending between a midpoint of the two side cover walls;
• a processing chamber comprising an inside of a processing chamber area and an outside of a processing chamber area;
• the inside of the processing chamber area being located between the back cover wall and the partition wall and the outside of the processing chamber area being located between the partition wall and the front cover wall;
• a workpiece mount for fixing a workpiece, wherein a part of the workpiece mount including at least one surface of the workpiece mount is arranged inside of the processing chamber;
• an opening arranged in a part of the partition wall for access to the inside of the processing chamber area from the access opening through the opening;
• and
• the partition wall comprising shutter doors movable between open positions where opening of the opening is performed so that the inside of the processing chamber area communicates with the outside of the processing chamber area, and closed positions where closing of the opening is performed so that the inside of the processing chamber area is isolated from the outside of the processing chamber area,
• wherein a part of the workpiece mount projects from the opening to the outside of the processing chamber area, and the closing is achieved by complete contact of the shutter doors with the workpiece mount in the closed positions, and
• wherein the part of the workpiece mount is located at the inside of the processing chamber area in the closed positions of the shutter doors, and an other part of the workpiece mount other than the part of the workpiece mount located at the inside of the processing chamber area is located at the outside of the processing chamber area.
