Moreover, using three-color substrates with exposed Si-H, SiO<sub>2</sub>, and SiN, transmission electron microscopy shows that one dose of MoF<sub>6</sub> is sufficient to achieve > 9 nm of TiO<sub>2</sub> ASD with S ≳ 0.926 on treated Si-H and SiN versus SiO<sub>2</sub>. A mechanism for MoF<sub>6</sub>-induced passivation is proposed, involving F transfer and removal of surface -OH groups.
