Abstract:
1. A producing method of a semiconductor device, comprising at least: loading at least one substrate formed on a surface thereof with a metal film into a processing chamber; and forming an oxide film including silicon on the surface of the substrate which includes the metal film; wherein the forming the oxide film includes: supplying a first reaction material including a silicon atom into the processing chamber while heating the substrate at a predetermined temperature; and supplying hydrogen and a second reaction material including an oxygen atom into the processing chamber while heating the substrate at the predetermined temperature; wherein in the forming the oxide film, supply of the first reaction material and supply of the second reaction material and the hydrogen are alternately repeated a plurality of times to form the oxide film; wherein in the forming the oxide film, after a thickness of the oxide film reaches a desired thickness, the oxide film is formed without supplying the processing chamber with hydrogen in the step supplying the hydrogen and the second reaction material, wherein the predetermined temperature is in a range of 100 to 450° C., the second reaction material is ozone, and when the predetermined temperature and a supply ratio of the ozone with respect to the hydrogen is defined as (T, O
