Ruthenium ald
WebMay 10, 2024 · The ultrathin and continuous ruthenium (Ru) film was deposited through an improved atomic layer deposition (ALD) process with a discrete feeding method (DFM), called DF-ALD, employing a cut-in purge step during the precursor feeding. The excess precursor molecules can be physically adsorbed onto the chemisorbed precursors on the … WebAchieving facile nucleation of noble metal films through atomic layer deposition (ALD) is extremely challenging. To this end, η4-2,3-dimethylbutadiene ruthenium(0) tricarbonyl (Ru(DMBD)(CO)3), a zero-valent complex, has recently been reported to achieve good nucleation by ALD at relatively low temperatures and mild reaction conditions.
