Abstract:
1. A method for fabricating a capacitor comprising: forming a first conductive layer; forming a dielectric layer on at least a portion of the first conductive layer; and forming a second conductive layer on the dielectric layer; wherein at least one of the first and second conductive layers comprises a vapor-deposited platinum-iridium film formed by chemical vapor co-deposition of platinum and iridium precursor compositions, wherein the vapor-deposited platinum-iridium film has the formula platinum(w):iridium(1−w), wherein w is in the range of about 0.99 to about 0.0, wherein the iridium precursor composition comprises one or more complexes of the formula:  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 y=1 to 4; and z=1 to 4.
