WebAdvantages: Moderately anisotropic using sidewall polymerization techniques (discussed later) , can be selective Disadvantages: Ion damage, residue 3.) Reactive Ion Etching: Advantages: Highly anisotropic using sidewall polymerization techniques, can be selective but less so than plasma etching due higher DC bias and longer mean free path. WebIt 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 improve the sidewall profile of the photoresist mask and improve the process uniformity. parker baby company birch bag diaper backpack
