More Information
Summary:A method for producing a pattern on a substrate includes providing at least one exposure of the pattern onto a layer of the substrate by a higher-precision lithography mechanism and providing at least one exposure of the pattern onto a layer of the substrate by a lower-precision lithography mechanism. The exposures can be done in either order, and additional exposures can be included. The higher-precision lithography mechanism can be immersion lithography and the lower-precision lithography mechanism can be dry lithography.
