A chemical liquid preparation method of preparing a TMAH-containing chemical liquid, including, a correspondence relationship preparing step of preparing a correspondence relationship between a supply flow rate ratio between an oxygen-containing gas and an inert-gas-containing gas and a convergent dissolved oxygen concentration in the TMAH-containing chemical liquid that is converged to when the oxygen-containing gas and the inert-gas-containing gas are supplied into the TMAH-containing chemical liquid; a concentration setting step of setting a target dissolved oxygen concentration in the TMAH-containing chemical liquid; a supply-flow-rate-ratio acquiring step of acquiring the supply flow rate ratio between the oxygen-containing gas and the inert-gas-containing gas corresponding to the target dissolved oxygen concentration in accordance with the correspondence relationship prepared in the correspondence relationship preparing step; and a gas supplying step of supplying the oxygen-containing gas and the inert-gas-containing gas with the supply flow rate ratio acquired in the supply-flow-rate-ratio acquiring step.

Chemical liquid preparation device, and substrate processing device

A chemical liquid preparation method of preparing a chemical liquid for treating a film formed on a substrate, including a gas dissolving process in which an oxygen-containing gas and an inert-gas-containing gas are dissolved in the chemical liquid by supplying the oxygen-containing gas which contains oxygen gas and the inert-gas-containing gas which contains an inert gas to a chemical liquid, wherein in the gas dissolving process, a dissolved oxygen concentration in the chemical liquid is adjusted by setting a mixing ratio between the oxygen-containing gas and the inert-gas-containing gas supplied to the chemical liquid as a mixing ratio corresponding to a predetermined target dissolved oxygen concentration.

Chemical liquid preparation method, chemical liquid preparation device, and substrate processing device

In a substrate processing apparatus of the present invention, when substrates are loaded into a chamber, a frame part formed integral with a substrate holding part is interposed between the chamber and a cover, thereby sealing the interior of the chamber. When the substrates are unloaded to above the chamber, the chamber and the cover are brought into a direct contact, thereby sealing the interior of the chamber. Hence, the interior of the chamber can be sealed satisfactorily when the substrates are loaded into the chamber, and when the substrates are unloaded to above the chamber.
