Zusammenfassung:Multi-beam lithography systems and methods of manufacturing semiconductor devices using the same are disclosed. For example, the method utilizes non-coincidence of boundaries of electrical fields emanating from chrome on glass or phase shifted mask features distributed over two masks for the optimization of lithographic process windows, side lobe suppression, or pattern orientation dependent process window optimization employing one mask with polarization rotating film on the backside.
