Lithography control
WebThis sensitivity to focus, particularly when there may be different planes for best focus for different features, indicates that EUV lithography will require very tight focus control. Independent of the mask 3D effects, it has also been found useful to have larger normalized image log-slopes (NILs) than typically used for optical lithography, 20 in order to … Web1 apr. 2011 · As leading edge lithography is moving to 2x-nm design rules, lithography control complements resolution as one of the main drivers and enablers to meet the very stringent overlay, focus and CD requirements. As part of ASML's holistic lithography roadmap, ASML is developing several application-specific optimization and control …
