Transport Parameters of $F^{(-)}$ Ions in Mixtures Ar/B$F_3$

POSTER

Abstract

Transport parameters of $F^{(-)}$ ions in mixtures Ar/B$F_3$ in DC fields were calculated by using Monte Carlo simulation technique. The scattering cross-section set for $F^{(-)}$ in B$F_3$ is assembled on the basis of Nanbu's technique separating elastic from reactive collisions. In this work we present transport coefficients for the conditions of low and moderate reduced electric fields E/N (E-electric field, N-gas density) accounting for the non-conservative collisions. This mixture is usual in plasma etching applications.
