Abstract

A substrate processing apparatus includes a photoresist coater applying a photoresist film on a substrate, a humidifier increasing an amount of moisture in an ambient to which the photoresist film on the substrate is exposed, and an exposer irradiating the photoresist film exposed to the ambient having the increased amount of moisture with light. The humidifier is disposed between the photoresist coater and the exposer.
