Abstract: Molybdenum (Mo) metal-on-metal (MoM) deposition methods for providing true bottom-up fill in vias and/or other gap features in device structures. These device structures contain metal at the bottom surface and have dielectric sidewalls. The deposition process provides molybdenum growth only, in some cases, on the metal film/layer to provide a selective process that can be called a metal-on-metal (MoM) process. The Mo MoM deposition process described herein are not limited to thin films (e.g., films less than 50 Å) and can be used to deposit thicker films (e.g., greater than 50 Å in some cases and greater than 200 Å in other useful cases) on metal surfaces while no, or substantially no, deposition is found on dielectric surfaces.

Abstract: A system and method for treating a deposition reactor are disclosed. The system and method remove or mitigate formation of residue in a gas-phase reactor used to deposit doped metal films, such as aluminum-doped titanium carbide films or aluminum-doped tantalum carbide films. The method includes a step of exposing a reaction chamber to a treatment reactant that mitigates formation of species that lead to residue formation.

Abstract: A method of depositing a material film on a substrate within a reaction chamber by a cyclical deposition process is disclosed. The method may include: contacting the substrate with a first vapor phase reactant and purging the reaction chamber with a first main purge. The method also includes: contacting the substrate with a second vapor phase reactant by two or more micro pulsing processes, wherein each micro pulsing process comprises: contacting the substrate with a micro pulse of a second vapor phase reactant; and purging the reaction chamber with a micro purge, wherein each of the micro pulses of the second vapor phase reactant provides a substantially constant concentration of the second vapor phase reactant into the reaction chamber. The method may also include; purging the reaction chamber with a second main purge. Device structures including a material film deposited by the methods of the disclosure are also disclosed.

Abstract: Methods of treating metal-containing thin films, such as films comprising titanium carbide, with a silane or a borane agent are provided. In some embodiments a film comprising titanium carbide is deposited on a substrate by an atomic layer deposition (ALD) process. The process may include a plurality of deposition cycles involving alternating and sequential pulses of a first source chemical that comprises titanium and at least one halide ligand, a second source chemical comprising metal and carbon, wherein the metal and the carbon from the second source chemical are incorporated into the thin film, and a third source chemical, wherein the third source chemical is a silane or borane that at least partially reduces oxidized portions of the titanium carbide layer formed by the first and second source chemicals. In some embodiments treatment forms a capping layer on the metal carbide film.

Abstract: Methods and systems for cleaning and treating a surface of a substrate. An exemplary method includes providing a substrate comprising a gap comprising a metal oxide and a dielectric material within a reaction chamber, and using a thermal process to selectively remove the metal oxide. Exemplary methods can further include a step of depositing a metal-containing material within the gap to at least partially fill the gap and using a direct plasma and treating a surface of the metal-containing material to remove oxygen from the surface of the metal-containing material. Exemplary systems can perform the methods.
