Etching gas
Noble gases like argon and helium are often used to dilute a gas mixture. This can be done to control etch rate or to improve other aspects of the etch. For ... ,In order to generate low-pressure plasma, the gas has to be ionized. The ionization happens by a glow charge. Those excitations happen by an external source, ...
