ABSTRACT:
A clamping frame for contact printers of working masks in the semiconductor industry enables the application of packings made of easily obtainable raw materials and limits tangential forces acting on masks of the original and copy. A first packing and a second packing with a supporting frame between both packings is provided. The supporting frame prevents transmission of tangential forces to packings which come in contact with masks of the original and of the copy.
