Abstract: Methods and systems for depositing vanadium nitride layers onto a surface of the substrate and structures and devices formed using the methods are disclosed. An exemplary method includes using a cyclical deposition process, depositing a vanadium nitride layer onto a surface of the substrate. The cyclical deposition process can include providing a vanadium halide precursor to the reaction chamber and separately providing a nitrogen reactant to the reaction chamber. The cyclical deposition process may desirably be a thermal cyclical deposition process.

Abstract: Methods for depositing a molybdenum metal film directly on a dielectric material surface of a substrate by a cyclical deposition process are disclosed. The methods may include: providing a substrate comprising a dielectric surface into a reaction chamber; and depositing a molybdenum metal film directly on the dielectric surface, wherein depositing comprises: contacting the substrate with a first vapor phase reactant comprising a molybdenum halide precursor; and contacting the substrate with a second vapor phase reactant comprising a reducing agent precursor. Semiconductor device structures including a molybdenum metal film disposed directly on a surface of a dielectric material deposited by the methods of the disclosure are also disclosed.

Abstract: A method of selectively depositing a material on a substrate with a first and second surface, the first surface being different than the second surface. The depositing of the material on the substrate comprises: supplying a bulk precursor comprising metal atoms, halogen atoms and at least one additional atom not being a metal or halogen atom to the substrate; and supplying a reactant to the substrate. The bulk precursor and the reactant have a reaction with the first surface relative to the second surface to form more material on the first surface than on the second surface.

Abstract: Vapor deposition processes such as atomic layer deposition (ALD) processes employing a deposition enhancing precursor can be used to form a variety of oxide and nitride films, including metal oxide, metal nitride, metal oxynitride, silicon oxide and silicon nitride films. For example, the methods can be used to deposit transition metal nitrides, transition metal oxides, and silicon oxides and nitrides. In some embodiments the deposition enhancing precursor comprises a Group II metal such as Mg, Sr, Ba or Ca. Atomic layer deposition processes may comprise a deposition cycle comprising a first sub-cycle in which a substrate is contacted with a deposition enhancing precursor and an oxygen or nitrogen reactant and a second sub-cycle in which the substrate is contacted with a metal or silicon precursor and an oxygen or nitrogen reactant. In some embodiments the methods advantageously enable improved thin film formation, for example increased deposition rates.
