Abstract:
A method of manufacturing a semiconductor structure, the method comprising:providing a semiconductor substrate or substrate assembly;providing a precursor composition comprising one or more complexes having a structure of the formula: ##STR5##wherein:M is a transition metal selected from the group consisting of IB, IIB, IIIB, IVB, VB, VIB, VIIB, and VIIIB metals;each R group is independently H, a hydrocarbyl group, a halogenated hydrocarbyl group, a halide, or a silylated hydrocarbyl group, with the proviso that R.sup.3 and R.sup.4 are both methyl and optionally the R groups are replaced by multiple bonds between backbone atoms in the structure;each L group is independently H, a hydrocarbyl group, a halogenated hydrocarbyl group, a silylated hydrocarbyl group, or a halide;x=1 to 3;n=0 to 4;y=0 to 4; andforming a metal-containing film from the precursor composition on a surface of the semiconductor substrate or substrate assembly.
