  • Publication number: 20240170283
    Abstract: A method for selective deposition of a silicon and oxygen containing dielectric film onto a substrate is disclosed. The method includes the steps of providing a substrate comprising a dielectric surface and a metal, or metal hydride, surface to a reactor. A halogenated silicon-containing compound may be introduced to the reactor to form a silicon-containing layer more abundantly on the dielectric surface than on the metal, or metal hydride, surface. A nitrogen source may be introduced into the reactor to react with the silicon-containing layer to form a silicon nitride film or a carbon doped silicon nitride film. An oxygen-containing source may be introduced to the reactor to react with the silicon nitride or carbon doped silicon nitride film to form the silicon and oxygen containing dielectric film.

  • 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.
