Abstract

A method for depositing a film on a substrate is provided. In one aspect, the method includes providing a metal-containing precursor to an activation zone, and activating the metal-containing precursor to form an activated precursor. The activated precursor gas is transported to a reaction chamber, and a film is deposited on the substrate using a cyclical deposition process, wherein the activated precursor gas and a reducing gas are alternately adsorbed on the substrate. Also provided is a method of depositing a film on a substrate using an activated reducing gas.
