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). If h f is WebPhotoresist descum is an additional gentle photoresist etching process after photoresist patterning and development. It is used to remove the residual photoresist scum left on the developed area. Such residual can prevent subsequent dry or wet etching steps and affect the uniformity of the etching rate across the wafer. Descum step can also ...
