LITHOGRAPHY ENGRAVING MACHINE

In some embodiments, the present disclosure relates a lithographic substrate marking tool. The lithographic substrate marking tool has a first lithographic exposure tool arranged within a shared housing and configured to generate a first type of electromagnetic radiation during a plurality of exposures. A mobile reticle has a plurality of different reticle fields respectively configured to block a portion of the first type of electromagnetic radiation to expose a substrate identification mark within a photosensitive material overlying a semiconductor substrate. A transversal element is configured to move the mobile reticle so that separate ones of the plurality of reticle fields are exposed onto the photosensitive material during separate ones of the plurality of exposures. The mobile reticle therefore allows for different strings of substrate identification marks to be formed within the photoresistive material using a same reticle, thereby economically providing the benefits of lithographic substrate marking.
