    摘要: The present invention provides a method for forming a silicon oxide film, with a substantially uniform film thickness and without being so influenced by dense sites and scattered sites in a pattern provided on an object to be processed, while keeping advantageous points of a plasma oxidation process performed under a lower-pressure and lower-oxygen-concentration condition. In this method, plasma of a processing gas is applied to a surface of the object having a concavo-convex pattern, in a processing chamber of a plasma processing apparatus, so as to oxidize silicon on the surface of the object, thereby forming the silicon oxide film. The plasma is generated under the condition that a ratio of oxygen in the processing gas is within a range of 0.1% to 10% and pressure is within a range of 0.133 Pa to 133.3 Pa. This plasma oxidation process is performed, with a plate, having a plurality of through-holes formed therein, being provided between a region for generating the plasma in the processing chamber and the object to be processed.

    摘要: The present invention provides a method for forming a silicon oxide film, which has excellent insulating properties and higher quality that can enhance a yield in manufacture of semiconductor devices, while keeping advantageous points in a plasma oxidation process. In this method, plasma is generated under a first process condition that a ratio of oxygen in a processing gas is 1% or less and pressure is within a range of 0.133 to 133 Pa, so as to form the silicon oxide film, by oxidizing silicon on a surface of an object to be processed including silicon as a main component, by using the plasma (first oxidation step). Following the first oxidation step, the plasma is generated under a second process condition that the ratio of oxygen in the processing gas is 20% or more and the pressure is within a range of 400 to 1333 Pa, so as to form an additional silicon oxide film, by further oxidizing the surface of the object to be processed, by using the plasma (second oxidation step).
