Numerical aperture lithography
Web1 jun. 2010 · NA: The numerical aperture is as high as it is today because of the adoption of a technology that was considered impractical until a few years ago—liquid immersion lithography. Here, the space between the optical system and the wafer is filled with a transparent liquid of index n, reducing the effective wavelength, or alternatively … Web1 feb. 2005 · Numerical aperture All optical lithographic systems operate in a gaseous ambient, either air or nitrogen, whose refractive index n is very close to 1. Therefore, increasing NA has meant increasing the acceptance angle of the lens, θ.
