Abstract:
A method for processing a substrate by utilizing a chemical reaction in a reaction enclosure including an outer tubular element and inner tubular element substantially coaxially arranged; a first end portion of the reaction enclosure in which a substrate carrying-in/carrying-out opening is provided and through which a reaction gas for processing a substrate is supplied; and a second end portion of the reaction enclosure from which internal atmosphere is discharged to a space between the outer tubular element and the inner tubular element and the atmosphere is discharged through the space, the method comprising:exhausting the atmosphere by using an atmosphere exhaust path for performing a substrate processing in a term during which a substrate is carried into the reaction enclosure through the substrate carrying-in/carrying-out opening within a time period during which an inside of the reaction enclosure is opened to an outside through the substrate carrying-in/carrying-out opening.
