Patent ID: 7715952

Claim:
A temperature setting method of a thermal processing plate for mounting and thermally processing a substrate thereon, the thermal processing plate being divided into a plurality of regions, and a temperature being settable for each of the regions, and a temperature correction value for adjusting an in-plane temperature of the thermal processing plate being settable for each of the regions of the thermal processing plate, said method comprising the steps of: measuring a processing state within a substrate, for a substrate for which a series of substrate processing including the thermal processing has been finished; calculating Zernike coefficients of a Zernike polynomial indicating a plurality of in-plane tendency components of the processing state of the substrate based on the measured values of the processing state within the substrate; calculating the temperature correction values for the regions of the thermal processing plate to bring the calculated Zernike coefficients close to 0 using a calculation model indicating a correlation between change amounts of the Zernike coefficients indicating the plurality of in-plane tendency components and the temperature correction values; and setting the temperature of each of the regions of the thermal processing plate based on each of the calculated temperature correction values.
