Abstract:
A process for forming a platinum coating on a substrate in a chemical vapor deposition reactor, comprising the steps of:(a) providing a platinum source reagent liquid solution, comprising:(i) at least one platinum source compound selected from the group consisting of compounds of the formulae:(A) RCpPt(IV)R'.sub.3 compounds, of the formula: ##STR9## wherein: R is selected from the group consisting of hydrogen, methyl, ethyl, i-propyl, n-propyl, n-butyl, i-butyl, t-butyl, trimethylsilyl and trimethylsilyl methyl; and each R' is independently selected from the group consisting of methyl, ethyl, i-propyl, n-propyl, n-butyl, i-butyl, t-butyl, trimethylsilyl and trimethylsilyl methyl; and(B) Pt(.beta.-diketonates).sub.2 of the formula: ##STR10## wherein: each R"" is independently selected from the group consisting of methyl, ethyl, n-propyl, i-propyl, n-butyl, i-butyl, t-butyl, trifluoromethyl, perfluoroethyl, and perfluoro-n-propyl, and(ii) a solvent medium therefor;(b) flash vaporizing the platinum source reagent liquid solution to form a platinum source reagent vapor therefrom;(c) transporting the platinum source reagent vapor to a chemical vapor deposition reactor; and(d) depositing platinum from the platinum source reagent vapor on the substrate in the chemical vapor deposition reactor, under chemical vapor deposition conditions effective therefor.
