Websolution, the etching mechanism is generally isotropic, that is, the lateral and vertical 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).
