METHOD OF SUBSTRATE TREATMENT, RECORDING MEDIUM AND SUBSTRATE TREATING APPARATUS

摘要

A method of processing a substrate by a substrate processing apparatus is disclosed. The substrate processing apparatus includes a processing container including a first space where a first processing gas or a second processing gas is supplied onto the substrate and a second space formed around the first space; a first exhaust unit configured to evacuate the first space; and a second exhaust unit configured to evacuate the second space. The method includes a first step of supplying the first processing gas into the first space; a second step of discharging the first processing gas from the first space; a third step of supplying the second processing gas into the first space; and a fourth step of discharging the second processing gas from the first space; wherein the pressure in the second space is adjusted by a pressure-adjusting gas supplied into the second space.
