Abstract
There is provided a substrate processing method for removing an oxide film formed on a surface of a substrate. The method includes (a) transforming the oxide film into a reaction by-product by supplying a halogen element-containing gas and a basic gas to the substrate accommodated in a processing chamber; and (b) sublimating the reaction by-product to remove the reaction by-product from the substrate by stopping the supply of the halogen element-containing gas into the processing chamber and supplying an inert gas into the processing chamber. The steps (a) and (b) are repeated a plurality of times.
