Abstract: The disclosure relates to methods of selectively depositing material comprising a group 3 to 6 transition metal on a first surface of a substrate relative to a second surface of the substrate by a cyclic deposition process. The method includes providing a substrate in a reaction chamber, providing a transition metal precursor into the reaction chamber in a vapor phase, wherein the transition metal precursor comprises an aromatic ligand and providing a second precursor into the reaction chamber in a vapor phase to deposit transition metal on the first surface of the substrate. The disclosure further relates to a transition metal layers, and to deposition assemblies.
