Patent ID: 7968825

Claim:
A temperature setting method of a thermal processing plate when mounting and thermally processing a substrate thereon, the thermal processing plate being divided into a plurality of regions, a temperature being settable for each of the regions, and a temperature correction value for adjusting an in-plane temperature being settable for each of the regions, said method comprising the steps of: measuring line widths of a resist pattern within the substrate for the substrate which has been subjected to a series of substrate processing including the thermal processing; calculating, from an in-plane tendency of the substrate of the measured line widths, an in-plane tendency improvable by changing the temperature correction value for each of the regions of the thermal processing plate, the in-plane tendency being a line width of the resist pattern at a plurality of points in a thickness direction within the substrate; and changing the temperature correction value for each of the regions of the thermal processing plate when a magnitude of the improvable in-plane tendency exceeds a threshold value set in advance.
