发明名称 Substrate processing method and substrate processing apparatus
摘要 A substrate processing method for removing an Si-based film on a surface of a substrate accommodated in a processing chamber includes a first step in which the Si-based film on the surface of the substrate is transformed into a reaction product by a gas containing a halogen element and an alkaline gas in the processing chamber and a second step in which the reaction product is vaporized in the processing chamber which is depressurized to a pressure lower than a pressure during the first step. The first step and the second step are repeated two or more times.

主权项 1. A substrate processing method for removing an Si-based film on a surface of a substrate accommodated in a processing chamber, the method comprising: a first step in which the Si-based film on the surface of the substrate is transformed into a reaction product by a gas containing a halogen element and an alkaline gas in the processing chamber; and a second step following the first step in which the reaction product is vaporized in the processing chamber which is depressurized to a pressure lower than a pressure during the first step, wherein the first step and the second step are sequentially repeated two or more times.
