WebOct 11, 2007 · Atomic layer deposition (ALD) and pulsed chemical vapor deposition (CVD) were used to make ruthenium (Ru) thin films from a volatile Ru amidinate precursor, bis ( -di- tert -butylacetamidinato)ruthenium (II) dicarbonyl. The CVD films were grown without any coreactant, while the ALD films used ammonia as a coreactant. WebAmidinate precursors such as Bis(N,N’-di-t-butylacetamidinato)ruthenium(II) dicarbonyl have characteristics that overcome some of these issues. Each amidinate ligand chelates the metal center through two metal-nitrogen bonds. These relatively weak M-N bonds and strong byproduct N-H bonds lead to lower ALD growth temperatures. general crown king molding jigWebJan 1, 2007 · Structural features of diruthenium amidinates are similar to those of monoruthenium amidinates; one of the ruthenium atoms is close to A with three-legged piano-stool structures in the coordinatively saturated C ( θ = 156–160°), whilst those of the coordinatively unsaturated analogues D are close to B with two-legged piano-stool … general crown king
