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 ...

Immersion lithography is a photolithography resolution enhancement technique for manufacturing integrated circuits (ICs) 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. Current immersion lithography tools use highl… WitrynaImmersion lithography is a photolithography resolution enhancement technique for manufacturing integrated circuits (ICs) 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.
