Abstract:
A plasma oxidation processing method is performed, on a structural object including a silicon layer and a refractory metal-containing layer, to form a silicon oxide film. A first plasma oxidation process is performed by use of a process gas including at least hydrogen gas and oxygen gas and a process pressure of 1.33 to 66.67 Pa. A second plasma oxidation process is performed by use of a process gas including at least hydrogen gas and oxygen gas and a process pressure of 133.3 to 1,333 Pa, after the first plasma oxidation process.
