Abstract:
A method of manufacturing a semiconductor structure, the method comprising:providing a semiconductor substrate or substrate assembly; providing a liquid precursor composition comprising one or more compounds of the formula (Formula 1): (diene)Ru(CO)3 â€ƒwherein â€œdieneâ€  refers to linear, branched, or cyclic dienes, bicyclic dienes, tricyclic dienes, fluorinated derivatives thereof, derivatives thereof additionally containing heteroatoms such as halide, Si, S, Se, P, As, N, or O, or combinations thereof; vaporizing the liquid precursor composition to form vaporized precursor composition; and directing the vaporized precursor composition in combination with at least one oxidizing gas less oxidizing than O2 toward the semiconductor substrate or substrate assembly to form a ruthenium metal film on a surface of the semiconductor substrate or substrate assembly.
