Classification: CPC G  H | IPC G  H

Claim 8:
9. A substrate processing apparatus, comprising:
a photoresist coater configured to apply a photoresist film on a substrate;
a humidifier configured to increase an amount of moisture in an ambient to which the photoresist film on the substrate is exposed;
an exposer configured to irradiate the photoresist film exposed to the ambient having the increased amount of moisture with light, wherein the humidifier is disposed between the photoresist coater and the exposer;
a dehumidifier configured to reduce an amount of moisture of an ambient to which the exposed substrate provided from the exposer is exposed;
a baking unit including a first baking chamber spaced apart from the dehumidifier by a first distance and a second baking chamber spaced apart from the dehumidifier by a second distance greater than the first distance, and configured to bake the exposed substrate by the exposer;
a transfer unit configured to transfer the substrate from the dehumidifier to the baking unit; and
a transfer speed controller configured to control a transfer speed of the substrate received from the dehumidifier being transferred in the transfer unit,
wherein the transfer speed controller controls the transfer unit to transfer the substrate from the dehumidifier to the first baking chamber at a first speed, and to transfer the substrate from the dehumidifier to the second baking chamber at a second speed faster than the first speed.
