Kind Code: A1 A method for forming an oxide film by heating a semiconductor wafer in a processing chamber in an oxidizing atmosphere to form an oxide film, which is capable of chemically activating hydrogen by a catalytic action. 6 while heating the reactor 26 to a temperature below the ignition point of hydrogen to generate hydrogen radicals, and reacting the hydrogen radicals with oxygen introduced into the processing chamber 1 to generate water. This is a method for forming an oxide film in which an oxide film is formed on a semiconductor wafer.
