Abstract:
1. A producing method of a semiconductor device, comprising: transferring a plurality of substrates into a processing chamber; supplying, in a state in which an inside of the processing chamber is heated and pressure in the processing chamber is lower than atmospheric pressure, oxygen-containing gas and hydrogen-containing gas into the processing chamber to process the plurality of substrates by oxidation; and transferring the plurality of the oxidation-processed substrates out from the processing chamber, wherein in the oxidation-processing, the hydrogen-containing gas is supplied from a plurality of locations of a region which horizontally surrounds a substrate arrangement region in which the plurality of substrates are arranged in the processing chamber, thereby allowing the oxygen-containing gas and the hydrogen-containing gas to react with each other at the plurality of locations of the region which horizontally surrounds the substrate arrangement region to generate a reaction species, and the oxidation-processing is performed with the reaction species; and flow rates of the hydrogen-containing gas supplied from the plurality of locations are different from each other.
