Abstract:
A method for forming a capacitor insulation film includes the step of depositing a monoatomic film made of a metal by supplying a metal source including the metal and no oxygen, and depositing a metal oxide film including the metal by using a CVD technique. The method provides the metal oxide film having higher film properties with a higher throughput.
