Abstract: A method for selectively depositing a metal film onto a substrate is disclosed. In particular, the method comprising flowing a metal precursor onto the substrate and flowing a non-metal precursor onto the substrate, while contacting the non-metal precursor with a hot wire. Specifically, a reaction between a tungsten precursor and a hydrogen precursor selectively forms a tungsten film, where the hydrogen precursor is excited by a tungsten hot wire.
