ABSTRACT:
The invention includes inserting an object to be processed into a processing vessel, which can be maintained vacuum, and making the processing vessel vacuum; performing a sequence of forming a ZrO2film on a substrate by alternately supplying zirconium source and an oxidizer into the processing vessel for a plurality of times and a sequence of forming SiO2film on the substrate by alternately supplying silicon source and an oxidizer into the processing vessel for one or more times, wherein the number of times of performing each of the sequences is adjusted such that Si concentration of the films is from about 1 atm % to about 4 atm %; and forming a zirconia-based film having a predetermined thickness by performing the film forming sequences for one or more cycles, wherein one cycle indicates that each of the ZrO2film forming sequences and the SiO2film forming sequences are repeated for the adjusted number of times of performances.
