Claim 0:
1. An apparatus for treating a substrate comprising:
at least one first process chamber configured to supply a developer onto the substrate;
at least one second process chamber configured to treat the substrate using a supercritical fluid;
a transfer chamber configured to transfer the substrate from the at least one first process chamber to the at least one second process chamber, while the developer supplied in the at least one first process chamber remains on the substrate;
a temperature and humidity control system configured to:
manage temperature and humidity of the transfer chamber by supplying a first gas of constant temperature and humidity into the transfer chamber, or
manage temperature and humidity of the at least one first process chamber by supplying a second gas of constant temperature and humidity into the at least one first process chamber; and

a valve box,
wherein the temperature and humidity control system comprises:
a gas providing unit located lower than the valve box and configured to provide the first gas of the constant temperature and humidity or the second gas of the constant temperature and humidity; and
at least one supply pipe connected to the gas providing unit and extending to the transfer chamber or the at least one first process chamber while passing through the valve box.
