Fig. 9: Predictions of the surface kinetic model for RIE.

a Time-evolution of the number of F atoms at 1100 total impacts and 90 eV Ar+ energy. The solid blue line, black dash-dot line, and red dashed line represent the number of F atoms in the mixed layer (I), surface (II), and bulk gas (III), respectively. b Time-evolution of Si etch rate (Ã…/s) at 1100 total impacts and 90 eV Ar+ energy.
