Witryna1 cze 2010 · The first exposure formed the 45-nm half-pitch “carrier” grid using 157-nm interference lithography (without immersion), while the second exposure provided the “modulation” cutout pattern using a 50-kV scanning electron beam lithography system (from M. Fritze et al., J. Vac. Sci. Technol. B 23, 2743-8, 2005). WitrynaImmersion lithography is a photolithography resolution enhancement technique that replaces the usual air gap between the final lens and the wafer surface with a liquid medium that has a refractive index greater than one. The resolution is increased by a factor equal to the refractive index of the liquid.
