    摘要: An exhausting method includes determining an exhaust flow rate of a process gas to be a predetermined value that is less than or equal to a gas flow rate corresponding to a maximum process capability of a purification system when the process gas is diluted to a lower explosive limit; calculating a pressure drop amount per unit time to maintain the determined exhaust flow rate of the process gas, based on a relation between the exhaust flow rate and the pressure drop amount per unit time; and evacuating an inside of the chamber to maintain the determined exhaust flow rate, while controlling the pressure through an automatic pressure control valve by setting a target pressure value to be updated as a control value of the automatic pressure control valve at every predetermined time interval so as to achieve a calculated pressure drop amount per unit time.

    摘要: A substrate processing method capable of controlling the internal pressure of a processing chamber to a high pressure and exhausting gases within the processing chamber at a high rate. The substrate processing method is for use in a substrate processing apparatus having a processing chamber, a supply unit supplying a processing gas into the processing chamber, a first pipe connected to the processing chamber at one end thereof, a turbo molecular pump disposed in the first pipe, a first shutoff valve disposed between the processing chamber and the turbo molecular pump in the first pipe, a second pipe connected to the processing chamber at one end thereof, a pressure control valve disposed in the second pipe, and a dry pump connected to the other end of the first pipe and to the other end of the second pipe. The substrate processing method comprises a pressure control step of controlling the internal pressure of the processing chamber using the pressure control valve after closing the first shutoff valve when performing a treatment on a substrate housed in the processing chamber; a first exhaust step of exhausting gases within the processing chamber through the second pipe using the dry pump by opening the pressure control valve after performing the treatment on the substrate; and a second exhaust step of exhausting gases within the processing chamber through the first pipe using the turbo molecular pump by closing the pressure control valve and opening the first shutoff valve after the first exhaust step.

    摘要: It is possible to prevent processing gases from being mixed when alternately supplying the processing gases while alternately switching the processing gases and to suppressed a transient phenomenon more efficiently as compared to conventional cases. When supplying at least two kinds of processing gases (e.g., a C4F6 gas and a C4F8 gas) into a processing chamber while alternately switching the at least two kinds of processing gases during a plasma process on a wafer, the supply of each processing gas can be alternately turned on and off by alternately setting an instruction flow rate of a mass flow controller to be a predetermined flow rate and a zero flow rate while a downstream opening/closing valve provided at a downstream side of the mass flow controller is open.
