Zusammenfassung:PROBLEM TO BE SOLVED: To selectively form a pure copper thin film by chemical vapor deposition on the metal or conductive surface of a substrate by bringing the substrate into contact with a volatile org. metal copper composite material having specified or higher vapor pressure at specified temp. and then carrying out vapor deposition in a specified temp. range. SOLUTION: The vapor deposition temp. is specified to rather low temp. as 100 to 190 deg.C. The volatile org. metal copper precursor material to be incontact with the substrate is expressed by formula having >=0.01mmHg vapor pressure at 100 deg.C. In the formula, R , R are independently 1 to 8C perfluoroalkyl groups, R is H or 1 to 8C perfluoroalkyl group, and L is a ligand for carbon monoxide, isonitrile or unsatd. hydrocarbon containing at least one nonaromatic unstad. bond. This volatile org. metal copper precursor is, for example, [Cu (hexafluoroacetylacetonate )1,5-cyclooctadiene.
