Most RF systems have a variable capacitor between the RF generator and the plasma. This is because in order to ensure maximum power transfer into the plasma, the input impedance of the plasma must equal the output impedance of the generator (normally 50 W).
1. Introduction In semiconductor fabrication using plasma, a capacitively coupled plasma (CCP) has been widely used in semiconductor processing, including etching, deposition, and ion implantation [ 1, 2 ]. The CCP has many advantages, such as a high ion bombarding energy on the electrode and the convenience of controlling the ion energy.
Abstract: A three-stage operational transconductance amplifier (OTA) stable for any load capacitor is introduced for the first time in literature. It contains a novel local ac feedback network in the intermediate stage in addition to the cascode-Miller compensation strategy.
By varying the value of this capacitor the effective impedance of the load (plasma + capacitor) can be made equal to 50 W. However the presence of this blocking capacitor introduces the constraint that no net current can flow during one RF cycle. In other words, the total net charge flow per RF cycle to both electrodes must sum to zero.
The only way for the plasma to achieve zero charge flow, therefore, is to have very different sheath potentials at the 2 electrodes. Consequently, the powered electrode charges up negatively until enough electrons are repelled for this constraint to be met.
