WebOptical Lithography. Photolithography is a patterning process in which a photosensitive polymer is selectively exposed to light through a mask, leaving a latent image in the … Webvertical etch rates are the same (Figure 6.3b). However, in pattern transfer operations, a resist pattern is defined by a lithographic process (Figure 6.3a), and anisotropic etching is needed to yield steep vertical walls (Figure 6.3c). If h f is assumed to be the thickness of the thin film and l the lateral distance etched
