On Relationships between Plasma Chemistry and Surface Reaction Kinetics Providing the Etching of Silicon in CF<sub>4</sub>, CHF<sub>3</sub>, and C<sub>4</sub>F<sub>8</sub> Gases Mixed with Oxygen

On Relationships between Plasma Chemistry and Surface Reaction Kinetics Providing the Etching of Silicon in CF<sub>4</sub>, CHF<sub>3</sub>, and C<sub>4</sub>F<sub>8</sub> Gases Mixed with Oxygen

In this work, we discuss the effects of component ratios on plasma characteristics, chemistry of active species, and silicon etching kinetics in CF<sub>4</sub> + O<sub>2</sub>, CHF<sub>3</sub> + O<sub>2</sub>, and C<sub>4</sub>F<sub>8...
