Abstract:
1. A substrate processing method comprising: generating a heated vapor by a bubbling; supplying the heated vapor to a vapor spray nozzle; housing a plurality of substrates in a container, wherein the container is configured to be able to open and close in a bottom thereof, is configured to be able to move along a first area in which a plurality of liquid tanks are provided in a second area arranged in parallel with the first area, and comprises a drain outlet at the bottom thereof; disposing the vapor spray nozzle in gaps between the plurality of substrates, thereby spraying the heated vapor onto rear surfaces of the plurality of substrates using the vapor spray nozzle after the housing the plurality of substrates in the container; taking the plurality of substrates out of the container after the spraying of the heated vapor; and dipping the plurality of substrates collectively into a liquid stored in one of the plurality of liquid tanks after the taking the plurality of substrates out of the container, wherein, in the generating of the heated vapor, a flow rate of a carrier gas of the bubbling is set in a range from 2 SLM to 3 SLM, the spraying of the heated vapor is carried out in the state where the plurality of substrates are housed in the container, and the whole of the container is moved in the second area in mid-course from completion of the housing the plurality of substrates in the container to initiation of the taking the plurality of substrates out of the container.
