| Outline of Final Research Achievements |
In this project, various precursors and solvents were examined for thin film formation of refractory metals by solution-based mist CVD method.
The case of using a source solution containing oxygen atoms in the precursor or solvent, an oxide thin film was obtained.However, when an acetonitrile solution of molybdenum chloride or tungsten chloride was used as a source, molybdenum carbide or tungsten carbide was formed above 650 oC. These results were in good agreement with the stable region considered from the equilibrium reaction of the precursor and solvent thermal decomposition products.
As described above, it was shown that mist CVD method can be applied to film formation not only oxide but also carbide or another compound by appropriately selecting precursor and solvent of source solution.
