    摘要: Disclosed are hafnium- and zirconium-containing precursors and methods of providing the same. The disclosed precursors include a ligand and at least one aliphatic group as substituent selected to have greater degrees of freedom than the usual substituents. The disclosed precursors may be used to deposit hafnium- or zirconium-containing layers using vapor deposition methods such as chemical vapor deposition or atomic layer deposition.
