Abstract

A silicon oxide film is formed in a processing chamber of a plasma processing apparatus by performing oxidation process, by using plasma to a processing object having a patterned irregularity, wherein the plasma is generated while high-frequency power is supplied to a mount table under the conditions that the oxygen content in a process gas is not less than 0.5% and less than 10% and the process pressure is 1.3 to 665 Pa.
