Abstract

A substrate liquid processing apparatus includes a processing tubwhich is configured to store therein a processing liquid and in which a processing of a substrate is performed by immersing the substrate in the stored processing liquid; a circulation lineconnected to the processing tub; a pumpprovided at the circulation line and configured to generate a flow of the processing liquid flowing out from the processing tub and returning back to the processing tub after passing through the circulation line; and a heaterprovided at the circulation line and configured to heat the processing liquid. At least two temperature sensorstoare provided at different positions within a circulation system including the processing tub and the circulation line. Controllersandcontrol a heat generation amount of the heater based on detection temperatures of the at least two temperature sensors.
