Abstract

Thin films of metallic iridium were grown by thermal metal organic chemical vapour deposition in a horizontal hot-wall reactor. The new solid compound Ir(2,2,6,6-tetramethyl-3,5-heptadione)(1,5-cyclooctadiene) was used as the iridium source. Evaporation rate experiments showed a rather poor volatility of this compound compared with Ir(acetylacetone)(1,5-cyclooctadiene). However, high growth rates of 0.25 μ h−1 could be realized at substrate temperatures of 350 °C using a graphite susceptor coated with iridium andisopropanol as a component of the reaction gas. The films were pure metallic, as shown by emission spectroscopy for chemical analysis, and had typical sheet resistances of 50 μω □−1.

    To obtain the quantitative data on the volatility of new complexes 2 and 3, we have carried out the measurements of the temperature dependencies of saturated vapor pressure using flow (transpiration) method as the closest to the experimental conditions in the flow type MOCVD reactors. For complex 1, some thermodynamic information on the sublimation process has been published earlier [29,36], but the data presented are not passably correlated. In particular, the sublimation enthalpy calculated from the Arrhenius plot of the evaporation rate gravimetrically determined by the decrease in the sample mass in the helium flow in the MOCVD evaporator in the temperature interval (388 – 408) K was (84 ± 4) kJ mol−1 [36].

    Due to these properties, the iridium films are used in several essential applications such as in catalysts [1], spark plugs [2], protective coatings [3,4] and implanted electrodes [5]. The thermal decomposition of metal–organic compound (precursor) vapors on heating surfaces (metal–organic chemical vapor deposition or MOCVD) is one of the most suitable methods to obtain thin film of refractory metals [6–8]. The investigation of thermodynamic properties of volatile precursors is demanded to optimize conditions of obtaining the target films by MOCVD.
