WitrynaThe first immersion fluids studied were to be used to extend 157-nm lithography , but it is immersion lithography at 193 nm (using water) that has been successfully commercialized. Water-based immersion lithography using 193 nm ArF illumination provides optical solutions as far as the 45-nm node (with a k 1 of 0.31), but is not able … WitrynaSilicone immersion oil is used for deep observations of live specimens. Silicone oil (ne≒1.40) closely matches the refractive index of cells (ne≒1.38) thereby minimizing spherical aberration when imaging through thick biological samples, resulting in bright, high-resolution images. Unlike water, silicone oil exhibits virtually no ...
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).
