Role of NH3 feeding period to realize high-quality nickel films by hot-wire-assisted atomic layer deposition
Highly pure Ni films were achieved using NiCp2 and NH2 radicals at 250C. To acquire low resistive Ni film, carbon content need to be reduced below 2.2 at. %. The incubation period for HW-ALD is short so very thin film can be formed.
