  • Publication number: 20200395221
    Abstract: A method of an embodiment includes (i) a step of supplying a first gas to a chamber, wherein the first gas is perfiuorotetraglyme gas, and (ii) a step of generating plasma of a second gas for etching of a porous film in order to etch the porous film at the same time as the step of supplying a first gas or after the step of supplying a first gas. Partial pressure of the first gas in the chamber or pressure of the first gas in the chamber when only the first gas is supplied to the chamber is higher than critical pressure causing capillary condensation of the first gas in the porous film and is lower than saturated vapor pressure of the first gas at a temperature of the workpiece during execution of the step of supplying a first gas.
