    Abstract: PURPOSE: An MOCVD(Metal Organic Chemical Vapor Deposition) method of tantalum oxide film is provided to allow a thin tantalum oxide film to be formed with high controllability in the film thickness, and to have excellent electric properties. CONSTITUTION: First(P2-P3), water vapor used as an oxidizing agent is supplied into a process container to cause moisture to be adsorbed on a surface of each semiconductor wafer(W). Then(P4-P5), PET gas used as a raw material gas is supplied into the process container and is caused to react with the moisture on the wafer at a process temperature of 200 DEG C, thereby forming an interface layer of tantalum oxide. Then(P6-P7), PET gas and oxygen gas are supplied into the process container at the same time, and are caused to react with each other at a process temperature of 410 DEG C, thereby forming a main layer of tantalum oxide on the interface layer.
