Abstract: Methods for selectively depositing on metallic surfaces are disclosed. Some embodiments of the disclosure utilize a hydrocarbon having at least two functional groups, at least one functional group selected from amino groups, hydroxyl groups, ether linkages or combinations thereof to form a self-assembled monolayer (SAM) on metallic surfaces.

Abstract: Described are methods of depositing a titanium aluminum nitride film on a substrate surface with a controlled amount of carbon. The methods include exposing a substrate surface to a titanium precursor, a nitrogen reactant and an aluminum precursor with purges of the unreacted titanium and aluminum precursors and unreacted nitrogen reactants between each exposure.

Abstract: Methods of forming devices comprise forming a dielectric layer on a substrate, the dielectric layer comprising at least one feature defining a gap including sidewalls and a bottom. The methods include selectively depositing a self-assembled monolayer (SAM) on the bottom of the gap. The SAM comprises a hydrocarbon having a formula of H—C≡C—R, wherein R is a linear alkyl chain or aryl group comprising from 1 to 20 carbon atoms or a formula of R′C═CR″, wherein R′ and R″ independently include a linear alkyl chain or aryl group comprising from 1 to 20 carbon atoms A barrier layer is formed on the SAM before selectively depositing a metal liner on the barrier layer. The SAM is removed after selectively depositing the metal liner on the barrier layer.
