Cctba precursor

Cctba precursor- A recent observation is that some of the Co 0 precursors such as CCTBA (Co003) undergo exothertic decomposition at temperature below 0 ° C while others undergo endothermic decomposition 105 Deposition on oxides appears to be profoundly different than deposition on metallic substrates, presumably due to differences between the surface electron density of nonMOCVD Co films as Cu seed replacement are deposited using CCTBA precursor Impact of different film properties on cobalt resistivity is evaluated and modeled Resistivity increase at low film thicknesses is mainly caused by surface roughness
