    Abstract: Methods of surface pretreatment during selective deposition are disclosed. One or more embodiment of the disclosure provides surface pretreatments which facilitate the removal of blocking layers. Some embodiments of the disclosure include a surface pretreatment comprising exposure of a substrate with a first surface and a second surface to modify the first surface, a blocking layer is deposited on the modified first surface, a film is selectively deposited on the second surface over the blocking layer, and the blocking layer is removed.

    Abstract: Methods of forming microelectronic 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 forming a hardmask on the dielectric layer; selectively depositing a self-assembled monolayer (SAM) on the bottom of the gap and on the hardmask; treating the microelectronic device with a plasma to remove the self-assembled monolayer (SAM) from the hardmask; forming a barrier layer on the dielectric layer and on the hardmask; selectively depositing a metal liner on the barrier layer on the sidewall; and performing a gap fill process on the metal liner.
