  • Publication number: 20230058258
    Abstract: An atomic layer deposition method for depositing a film into surface features of a substrate is disclosed. The method may include the step of placing the substrate having surface features into a reactor. An organic passivation agent may be introduced into the 5 reactor, which may react with a portion of exposed hydroxyl radicals within the surface features. Subsequently, unreacted organic passivation agent may be purged, and then a precursor may be introduced. The precursor may react with the remaining exposed hydroxyl radicals that did not interact with the organic passivation agent. Subsequently, the unreacted precursor may be purged, and an oxygen source or a nitrogen source may 10 be introduced into the reactor to form a film within the surface features.
