Ni thin films were deposited by atomic layer deposition ALD using bis dimethylamino-2-methyl-2-butoxo nickel Ni dmamb 2
as a precursor and NH3 gas as a reactant. The growth characteristics and film properties of ALD Ni were investigated. Low-
resistivity films were deposited on Si and SiO2 substrates, producing high-purity Ni films with a small amount of oxygen and
negligible amounts of nitrogen and carbon. Additionally, ALD Ni showed excellent conformality in nanoscale via holes. Utilizing
this conformality, Ni/Si core/shell nanowires wit
