WebMar 22, 2007 · Another advantage of the immersion technique is that it enables the lens designs with numerical apertures greater than 1.0 - hyper-NA 193nm immersion lithography. The NA of a "dry" exposure system does not go beyond 1.0; otherwise, the exposure light will be totally reflected back at the lens/air interface -- totally internal … Web193 nm immersion lithography optical projection systems using conventional UV optical materials and water as the immersion fluid, with planar lens/fluid interfaces, have a practical numerical aperture (NA) limit near 1.3. The bottleneck for pushing the NA further is the refractive index of the final lens element. Higher-index immersion fluids
