Abstract:
A volatile metal (M) precursor compound for the chemical vapor deposition (CVD) of metal to selected surfaces, the precursor compound comprising:M.sup.+1 (hexafluoroacetylacetonate); andan allyl-derived ligand including a first carbon atom having a first bond to a methylene and a second bond to an H, and a second carbon double bonded to said first carbon atom, having a third bond to an H and a fourth bond to an H, and in which said methylene has a fifth bond selected from the group consisting of alkyl, phenyl, trialkoxylsilane, halodialkylsilane, dihaloalkylsilane, trihalosilane, triphenylsilane, alkoxyl, halogen, chloroformate, cynanide, cycloalkyl, cycloalkylamine, alkyl ether, isocyanate, and pentafluorobenzene, whereby a stable precursor capable of high metal deposition rates is formed.
