    Abstract: The disclosure relates to methods of selectively depositing material comprising molybdenum on a first surface of a substrate relative to a second surface of the substrate by a cyclic deposition process. The methods comprise providing a substrate in a reaction chamber, and performing at least one super-cycle comprising a halide sub-cycle and an oxyhalide sub-cycle. The halide sub-cycle comprises providing molybdenum halide precursor into the reaction chamber in a vapor phase, and the oxyhalide sub-cycle comprises providing molybdenum oxyhalide precursor into the reaction chamber in a vapor phase and providing a reactant into the reaction chamber to deposit material comprising molybdenum on the first surface of the substrate. The disclosure further relates to molybdenum layer, to a semiconductor structure and a device, and to vapor deposition assemblies for selectively depositing material comprising molybdenum on a substrate.

    Abstract: The current disclosure relates to methods for forming a film comprising transition metal on a substrate. The disclosure further relates to a transition metal layer, to a structure and a device comprising a layer that comprises a transition metal. In the method, transition metal is deposited on a substrate by a cyclic deposition process. The method comprises providing a substrate in a reactor chamber and executing a cyclical deposition process. The cyclical deposition process comprises the steps of providing a transition metal precursor in vapor phase into the reaction chamber and providing a halogen precursor in vapor phase into the reaction chamber to form a film comprising elemental transition metal on a substrate. The halogen precursor comprises only one halogen atom. The disclosure further relates to a deposition assembly for depositing a material comprising transition metal on a substrate.

    Abstract: A method for forming ultraviolet (UV) radiation responsive metal-oxide containing film is disclosed. The method may include, depositing an UV radiation responsive metal oxide-containing film over a substrate by, heating the substrate to a deposition temperature of less than 400° C., contacting the substrate with a first vapor phase reactant comprising a metal component, a hydrogen component, and a carbon component, and contacting the substrate with a second vapor phase reactant comprising an oxygen containing precursor, wherein regions of the UV radiation responsive metal oxide-containing film have a first etch rate after UV irradiation and regions of the UV radiation responsive metal oxide-containing film not irradiated with UV radiation have a second etch rate, wherein the second etch rate is different from the first etch rate.
