摘要:
A method for manufacturing a capacitor electrode by removing a silicon oxide film on a surface of a substrate, including: transforming the silicon oxide film into a reaction product by supplying a gas containing a halogen element to chemically react with the silicon oxide film while controlling temperature of the substrate to a first process temperature; and removing the silicon oxide film transformed to the reaction product while controlling the temperature of the substrate to a second process temperature higher than the first process temperature. The silicon oxide film is a BPSG film.
