Patent ID: 8216642

Claim:
A method of manufacturing a thin film comprising: transporting an object to be treated into a vacuum atmosphere in which a catalyst is disposed inside a vacuum chamber with one face for the object to be treated facing the catalyst, performing a raw material gas introduction step and a reactive gas introduction step, wherein the raw material gas introduction step comprises introducing raw material gas into the vacuum chamber, wherein the reactive gas introduction step comprises introducing a reactive gas including a hydrogen atom in its chemical structure into the vacuum chamber during a time when the introduction of the raw material gas is halted, and bringing the reactive gas into contact with the catalyst through which an electronic current is flowed to heat to a temperature at which radicals are generated from the reactive gas, wherein the raw material gas introduction step and the reactive gas introduction step are performed alternately so as to form a thin film on the surface of the object to be treated by the radicals and the raw material gas undergoing a chemical vapor deposition reaction on the object to be treated positioned in the vacuum atmosphere inside the vacuum chamber, wherein the raw material gas is Ta[NC(CH 3 ) 2 C 2 H 5 ][N(CH 3 ) 2 ] 3 , and wherein a metallic film having Ta is formed as the thin film.
