  • Publication number: 20240133032
    Abstract: The current disclosure relates to methods of depositing transition metal on a substrate. The disclosure further relates to a transition metal layer, to a structure and to a device comprising a transition metal layer. In the method, transition metal is deposited on a substrate by a cyclical deposition process, and the method comprises providing a substrate in a reaction chamber, providing a transition metal precursor to the reaction chamber in a vapor phase and providing a reactant to the reaction chamber in a vapor phase to form transition metal on the substrate. The transition metal precursor comprises a transition metal from any of groups 4 to 6, and the reactant comprises a group 14 element selected from Si, Ge or Sn.

  • Publication number: 20220254642
    Abstract: The current disclosure relates to methods and apparatuses for the manufacture of semiconductor devices In the disclosure, a transition metal-containing material is selectively deposited on a substrate by a cyclic deposition process. The deposition method comprises providing a substrate in a reaction chamber, wherein the substrate comprises a first surface comprising a first material, and a second surface comprising a second material. A transition metal precursor comprising a transition metal halide compound is provided in the reaction chamber in vapor phase and a second precursor is provided in the reaction chamber in vapor phase to deposit a transition metal-containing material on the first surface relative to the second surface. A transition metal compound may comprise an adduct-forming ligand. Further, a deposition assembly for depositing transition metal-comprising material is disclosed.
