Abstract: Provided is a heating unit including: a heating plate for heating a substrate; a heater installed in the heating plate; and a control unit for controlling the heater, in which wherein the heater includes: a first heater; and a second heater installed at a position different from a position of the first heater, and the control unit includes: a power source for transferring power to at least one of the first heater and the second heater; and a switching module for connecting the first heater and the second heater in series or connecting the first heater and the second heater in parallel.

Abstract: An apparatus for treating a substrate is disclosed. The apparatus for treating the substrate includes a housing having a treatment space inside the housing, a plate to support the substrate inside the housing, a heating member provided inside the plate to heat the substrate and including a plurality of heating zones, a temperature measuring member to measure a temperature of the substrate with respect to each of the plurality of heating zones of the heating member, and a control unit to control a temperature for the heating member in a dynamic section of a temperature change graph measured in the temperature measuring member. The control unit performs temperature control with respect to each of the plurality of heating zones of the heating member to uniformize the thickness of the thin film on the substrate.
