Abstract:
In-situ methods for depositing a metal film without the use of a barrier layer are disclosed. Some embodiments comprise forming an amorphous nucleation layer comprising one or more of silicon or boron and forming a metal layer on the nucleation layer. These processes are performed without an air break between processes.
