WebLens Mask Projection Lens Wafer Numerical Aperture NA=sinθo Lithography Handbook Minimum feature size (resolution) MFS = k1λ/NA k1 ≈ 0.8 (resist/enhancements) Depth … WebA lithography (more formally known as ‘photolithography’) system is essentially a projection system. Light is projected through a blueprint of the pattern that will be printed (known as a ‘mask’ or ‘reticle’). With the pattern encoded in the light, the system’s optics shrink and focus the pattern onto a photosensitive silicon wafer.
