Plasma Etching

Plasma etching is widely used for etching nanoscale features because it can produce vertical sidewall profiles with little or no undercut. An example is shown in Figure 5.19.This anisotropic feature can be further enhanced by allowing the deposition of certain passivating films to occur along vertical sidewalls during the plasma reaction.

Etching with plasma: Decomposition of oxide layers ...

Plasma etching is the removal of material from surfaces via plasma processes. It is also described as dry etching because conventional etching processes are carried out with wet chemical methods using aggressive acids. The plasmas of the process gases change the aggregate state of the material to be etched from solid to gaseous, and the vacuum pump extracts the gaseous products.
