Abstract

Sulfur hexafluoride (SF₆) is commonly used as a gaseous dielectric and as a plasma etching gas. In this work, the state of knowledge on electron-interaction cross sections and electron-swarm parameters in SF₆ is comprehensively reviewed and critically assessed. Cross sections are presented and discussed for the following scattering processes: total electron scattering; differential elastic; elastic integral; elastic momentum; total vibrational; total and partial ionization; total dissociative and nondissociative electron attachment; dissociation into neutrals. Coefficients for electron-impact ionization, effective ionization, electron attachment , electron drift, and electron diffusion are also reviewed and assessed.
