N-METAL FILM DEPOSITION WITH INITIATION LAYER

摘要

Provided are methods of depositing N-Metals onto a substrate. Some methods comprise providing an initiation layer of TaM or TiM layer on a substrate, wherein M is selected from aluminum, carbon, noble metals, gallium, silicon, germanium and combinations thereof; and exposing the substrate having the TaM or TiM layer to a treatment process comprising soaking the surface of the substrate with a reducing agent to provided a treated initiation layer.
