This work discusses the plasma characteristics and chemistry in CF4 + Ar, Cl2 + Ar and HBr + Ar gas systems under one and the same operating condition. The investigation was carried out using the combination of plasma diagnostics by Langmuir probes and 0-dimensional plasma modeling in the planar inductively coupled plasma reactor at constant gas pressure (10 mTorr), input power (800 W) and bias power (300 W), but with variable (0–80%) Ar fraction in a feed gas.The main attention was attracted to the parameters influenc-ing the steady-state densities of plasma active species (electron temperature, electron density, electron-impact rate coefficients) and the kinetics of ion-assisted chemical reaction (fluxes of halogen atoms, ion bombardment energy, ion energy flux).

Key words: CF4, Cl2, HBr, plasma, rate coefficient, reaction rate, halogen atom flux, ion energy flux
