WebIn order to obtain an anisotropic etching profile, the surface reaction is required to proceed only in the vertical direction. There are a few ways to achieve anisotropic etching. The sidewall protection method is the first approach discussed. Subsequently, ion-assisted reactions as a second approach will be described.
