The properties of (HFA)Cu . l,5-COD complex, being the prospective CVD-precursor for thin copper films for microelectronics, were investigated by UV (He 1) photoelectron, X-ray fluorescent spectroscopy and mass-spectroscopy together with ab initio calculations in approximation of density functional theory. The detailed analysis of energy and structure of highest occupied MO'S of (HFA)Cu . 1,5-COD was carried out. The thermodynamical and kinetical parameters of thermolysis reaction for (HFA)Cu . l,5-COD were determined and discussed. The initial stages of growth of thin copper films on the basis of this precursor (Si3N4 substrates) were studied by high-resolution transmission electron microscopy and X-ray photoelectron spectroscopy.
