摘要： In the present invention, the line widths within a substrate of an etching pattern are measured for a substrate for which photolithography processing and an etching treatment thereafter have been finished. The line width measurement results are converted into the line widths of a resist pattern using relational expressions which have been obtained in advance. From the converted line widths of the resist pattern, coefficients of a polynomial function indicating variations within the substrate are calculated. Next, a function between line width correction amounts for the resist pattern and temperature correction values is used to calculate temperature correction values for the regions of the thermal plate to bring the coefficients of the polynomial function close to zero. Based on each of the calculated temperature correction values, the temperature for each of the regions is set.

摘要： Temperature setting of a thermal plate is performed so that the line width of a resist pattern is uniformly formed within a wafer. The thermal plate of a PEB unit is divided into a plurality of thermal plate regions so that the temperature can be set for each of the thermal plate regions. A temperature correction value for adjusting the temperature within the wafer mounted on the thermal plate is set for each of the thermal plate regions of the thermal plate. The temperature correction value for each of the thermal plate regions of the thermal plate is set after calculation by a calculation model created from a correlation between a line width of the resist pattern formed by thermal processing on the thermal plate and the temperature correction value. The calculation model M calculates the temperature correction value to make the line width uniform within the wafer, based on a line width measured value of the resist pattern.
