Abstract
A method to selectively deposit a barrier layer on dielectric material that surrounds one or more metal interconnects on a substrate is disclosed. The barrier layer is selectively deposited on the metal film using a cyclical deposition process including a predetermined number of deposition cycles followed by a purge step. Each deposition cycle comprises alternately adsorbing a refractory metal-containing precursor and a reducing gas on the dielectric material formed on the substrate in a process chamber.
