Weblithography using the following Rayleigh’s formula (3); R = k1 × λ/NA, where λ is the exposure wavelength, NA is the numerical aperture of projection optics, and k1 is a constant depending on the lithography process. As k1 decreases, the lithography becomes more difficult. The theoretical lower limit of k1 is 0.25 for the projection
