Enhancing Si<sub>3</sub>N<sub>4</sub> Selectivity over SiO<sub>2</sub> in Low-RF Power NF<sub>3</sub>–O<sub>2</sub> Reactive Ion Etching: The Effect of NO Surface Reaction

Highly selective etching of silicon nitride (Si<sub>3</sub>N<sub>4</sub>) and silicon dioxide (SiO<sub>2</sub>) has received considerable attention from the semiconductor community owing to its precise patterning and cost efficiency. We investigated the etching se...
