Abstract

Methods of depositing a metal film are discussed. A metal film is formed on the bottom of feature having a metal bottom and dielectric sidewalls. Formation of the metal film comprises exposure to a metal precursor and an alkyl halide catalyst while the substrate is maintained at a deposition temperature. The metal precursor has a decomposition temperature above the deposition temperature. The alkyl halide comprises carbon and halogen, and the halogen comprises bromine or iodine.
