Abstract
A system acquires a temperature TB of a temperature-controlling medium before a temperature change during execution of a plurality of processes n (n is identifier of process and is natural number that is greater than one) in each of which heat is input to a substrate placed on a placement surface of a stage, wherein the placement surface on which the substrate is placed is formed on the stage, a flow path through which the temperature-controlling medium having an adjusted temperature flows is formed in the stage, and a discharge port via which heat transfer gas is discharged toward the placement surface is formed in the stage; and for each of the processes n, a pressure Pof heat transfer gas supplied to the discharge port and a temperature TWof the substrate. The system also adjusts a pressure of heat transfer gas so as to control temperature of substrate.
