Abstract:
1. A film forming method comprising the steps of: producing a gas-state monovalent carboxylic acid metal salt by reacting a solid-state bivalent carboxylic acid metal salt with a carboxylic acid using a heat in a vacuum; forming a layer of solid-state monovalent carboxylic acid metal salt on a substrate as a precursor without thermal decomposition by introducing gas-state monovalent carboxylic acid metal salt on the substrate; and after forming the layer of solid-state monovalent carboxylic acid metal salt on the substrate, providing energy to the substrate formed with the layer of solid-state monovalent carboxylic acid metal salt, thereby decomposing a carboxylic acid salt in the layer of solid-state monovalent carboxylic acid metal salt on the substrate to form a metallic film on the substrate.
