Immersion Lithography - SPIE

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.

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 now in use and is expected to allow lenses to be made with numerical apertures greater than 1.0. Lenses with NAs above 1.2 or 1.3 seem likely. If an immersion fluid with a refractive index closer to that of the photoresist can be found, numerical apertures of up to 1.5 might be possible.
