Provided are a semiconductor device manufacturing method by which a semiconductor device in which a threshold voltage is suppressed from changing can be manufactured, a substrate processing method and apparatus, a non-transitory computer-readable recording medium, and the semiconductor device. The semiconductor device manufacturing method includes forming an amorphous first oxide film including a first element on a substrate, and modifying the first oxide film to an amorphous second oxide film including the first element and a second element different from the first element by adding the second element to the first oxide film. The first element includes at least one element selected from a group consisting of aluminum, yttrium and lanthanum. A concentration of the second element in the second oxide film is controlled to be lower than that of the first element in the second oxide film. |
