Classification: CPC G  H | IPC G  H

Claim 14:
15. A substrate processing apparatus comprising:
a photoresist coater configured to apply a photoresist film on a substrate;
an exposer configured to irradiate the photoresist film with extreme ultraviolet (EUV) light;
a photoresist develop unit configured to develop the photoresist film on the substrate exposed by the exposer;
a baking unit configured to bake the substrate with developed photoresist;
a humidifier configured to increase an amount of moisture in an ambient to which the substrate is exposed; and
a dehumidifier configured to reduce an amount of moisture in an ambient to which the substrate is exposed,
wherein the baking unit includes a plurality of baking chambers facing the photoresist coater and configured to bake the substrate,
wherein the humidifier is stacked with the plurality of baking chambers, and
wherein the dehumidifier is disposed between the photoresist coater and the exposer.
