Abstract:
1. A heating device comprising: a heating part including a plurality of two-dimensionally arranged heating elements in a lattice form configured to perform a heating process on an exposed substrate prior to a developing process to form a resist pattern on the exposed substrate using a resist film; a seating part provided at an upper side of the heating part and configured to place the exposed substrate; and a control part configured to correct a setting temperature of the heating part based on a temperature correction value, and to control the heating part based on the corrected setting temperature, during a heating process of the exposed substrate by the heating part, wherein the temperature correction value is obtained in advance from a measured line width of a resist pattern formed on a substrate separately processed from the exposed substrate through a heating process by the heating part and a subsequent developing process, and the control part is configured to control each of the plurality of two-dimensionally arranged heating elements individually based on the corrected setting temperature.
