Abstract

A film forming apparatus, which forms a thin film formed of a metal oxide on a substrate by alternately supplying a raw material gas formed of an organic material containing a metal and an oxidation gas for oxidizing the organic material to the substrate a plurality of times, within a reaction vessel under a vacuum atmosphere, is provided. A control part outputs a control signal for comparing a moisture concentration detected by a moisture detection part with a set value after initiation of a step of supplying the oxidation gas and before starting a step of supplying the raw material gas, and when the moisture concentration exceeds a set value, for increasing a substitution operation of an atmosphere substitution step.
