Abstract:
1. A barrier film producing method for forming a barrier film composed of a metal compound containing a metallic element on a surface of an object to be film formed, comprising the steps of: disposing a catalytic material and the object to be film formed inside a vacuum chamber and heating the catalytic material; an introducing step for introducing a gas of a metallic material, containing a metallic element in the chemical structure, between the catalytic material and the object to be film formed; a producing step for contacting a reactive gas with the catalytic material in order to produce radicals of the reactive gas, the reactive gas being adapted to react with the metallic material gas to produce the metallic compound; repeating the introducing step and the producing step, wherein a back-flow preventing gas, which does not react with the metallic material gas or the reactive gas, is introduced into the vacuum chamber, and the metallic material gas and the reactive gas are introduced during a flow of the back-flow preventing gas in a state such that the flow of the back-flow preventing gas is formed, flowing from a side of the catalytic material to a side of the object to be film formed.
