Abstract: Methods of producing metal-containing thin films with low impurity contents on a substrate by atomic layer deposition (ALD) are provided. The methods preferably comprise contacting a substrate with alternating and sequential pulses of a metal source chemical, a second source chemical and a deposition enhancing agent. The deposition enhancing agent is preferably selected from the group consisting of hydrocarbons, hydrogen, hydrogen plasma, hydrogen radicals, silanes, germanium compounds, nitrogen compounds, and boron compounds. In some embodiments, the deposition-enhancing agent reacts with halide contaminants in the growing thin film, improving film properties.

Abstract: The invention relates generally to processes for enhancing the deposition of noble metal thin films on a substrate by atomic layer deposition. Treatment with gaseous halides or metalorganic compounds reduces the incubation time for deposition of noble metals on particular surfaces. The methods may be utilized to facilitate selective deposition. For example, selective deposition of noble metals on high-k materials relative to insulators can be enhanced by pretreatment with halide reactants. In addition, halide treatment can be used to avoid deposition on the quartz walls of the reaction chamber.
