Abstract
A plasma oxidizing method includes a step of placing an object to be processed and having a surface containing silicon on a susceptor disposed in a processing vessel of a plasma processing apparatus, a step of producing a plasma from a processing gas containing oxygen in the processing vessel, a step of supplying high-frequency electric power to the susceptor and applying a high-frequency bias to the object to be processed when the plasma is produced, and a step of forming a silicon oxide film by oxidizing silicon in the surface of the object to be processed by the plasma.
