Capacitively Coupled Plasma Etching (CCP)
Capacitively coupled plasma is a plasma generated between two electrodes while reactive gases are fed into the chamber. The electrodes form the parallel plates of a capacitor and hence the resulting plasma is called a capacitively coupled plasma. RF power is applied to one of the electrodes while the other is grounded. In this mode, ions are accelerated from the plasma
