Abstract: A manufacturing method includes loading a substrate into a chamber, the substrate including oxide semiconductor; configuring a temperature in the chamber to a first temperature; supplying an oxidizing gas into the chamber; lowering the temperature in the chamber from the first temperature; stopping supplying the oxidizing gas into the chamber after lowering the temperature; and unloading the substrate from the chamber after the temperature in the chamber reaches a second temperature lower than the first temperature.
