Abstract: Disclosed is a method for treating a substrate in a plurality of chambers. The substrate treating method may include performing liquid treatment on a substrate located in a chamber through a supply line for connecting a circulation line and each of the plurality of chambers while the liquid circulates in the circulation line, wherein a flow rate per unit time of the liquid flowing downstream of a valve provided in the supply line is constantly maintained at a reference flow rate, and controlling an upstream flow rate which is a flow rate per unit time of the liquid flowing upstream of the circulation line rather than the supply lines or a downstream flow rate which is a flow rate per unit time of the liquid flowing downstream of the circulation line rather than the supply lines based on a distribution flow rate which is a flow rate per unit time of the liquid flowing upstream of the valve to maintain the reference flow rate.

Abstract: Provided are a treating liquid providing unit capable of predicting a temperature change of a substrate treating liquid by adding an inflow amount or consumption amount of the substrate treating liquid as a control factor, and a substrate treating apparatus including the same. The treating liquid providing unit includes a treating liquid storage module for storing the substrate treating liquid, a treating liquid heating module for heating the substrate treating liquid, a treating liquid discharging module for discharging the substrate treating liquid, a treating liquid supplying module for supplying the substrate treating liquid to the treating liquid storage module when the substrate treating liquid is discharged, and a control module for predicting the temperature of the substrate treating liquid remaining in the treating liquid storage module based on the inflow amount of the substrate treating liquid.
