Abstract:
1. A temperature setting method for a thermal processing plate mounting and thermally processing a substrate thereon, the thermal processing plate being divided into a plurality of regions, and a temperature being capable of being set for each of the regions, and a temperature correction value for adjusting an in-plane temperature of the thermal processing plate being capable of being set for each of the regions of the thermal processing plate, said method comprising the steps of: measuring physical attributes of an etching pattern within the substrate for a substrate for which a series of photolithography processing including the thermal processing on the thermal processing plate and an etching treatment thereafter have been finished; calculating correction amounts of a resist pattern within the substrate from a measurement result of the physical attributes of the etching pattern within the substrate using first functions relating the physical attributes of the etching pattern within the substrate to physical attributes of the resist pattern after the photolithography processing; calculating the temperature correction values for the regions of the thermal processing plate from a calculation result of the physical attributes of the resist pattern within the substrate using a second function relating the correction amounts for the physical attributes of the resist pattern to the temperature correction values for the thermal processing plate; and setting the temperature for each of the regions of the thermal processing plate by each of the calculated temperature correction values.
