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 of the formula:L.sub.y RhY.sub.z,wherein:each L group is independently a neutral or anionic ligand;each Y group is independently a pi bonding ligand selected from the group of CO, NO, CN, CS, N.sub.2, PX.sub.3, PR.sub.3, P(OR).sub.3, AsX.sub.3, AsR.sub.3, As(OR).sub.3, SbX.sub.3, SbR.sub.3, Sb(OR).sub.3, NH.sub.x R.sub.3-x, CNR, and RCN, wherein R is an organic group, X is a halide, and x=0 to 3;y=1 to 4; andz=0 to 4;providing a nonhydrogen reaction gas; andforming a rhodium-containing layer from the precursor composition in the presence of the nonhydrogen reaction gas on a surface of the semiconductor substrate or substrate assembly.
