Abstract: A bonding system includes a bonding device, an inspection device and a controller. The bonding device forms a combined substrate by bonding a first substrate and a second substrate to each other. The inspection device inspects the combined substrate. The controller controls the inspection device. The controller includes a measurement controller, a comparison unit and a re-measurement controller. The measurement controller causes the inspection device to measure the combined substrate at a first number of measurement points. The comparison unit compares, with a reference, an inspection result including a deviation amount between the first substrate and the second substrate in the combined substrate based on a measurement result. The re-measurement controller causes the inspection device to re-measure the combined substrate at a second number of measurement points greater than the first number of measurement points based on a comparison result obtained by the comparison unit.

Abstract: In the present invention, temperature drop amounts of heating plate regions when the substrate is mounted on a heating plate are detected to detect a warped state of the substrate. From the temperature drop amounts of the heating plate regions, correction values for set temperatures of the heating plate regions are calculated. The calculation of the correction values for the set temperatures of the heating plate regions is performed by estimating steady temperatures within the substrate to be heat-processed on the heating plate from the temperature drop amounts of the heating plate regions using a correlation obtained in advance. From the estimated steady temperatures within the substrate and the temperature drop amounts of the heating regions, the correction values for the set temperatures of the heating plate regions are calculated. Based on the correction values for the set temperatures, the set temperatures of the heating plate regions are changed.

Abstract: In the present invention, for measurement of line widths, for example, at 36 locations within a substrate processed in a coating and developing treatment system, the 36 measurement points are divided and, for example, six substrates are used to measure the line widths at all of measurement points. In this event, the line widths at six measurement points are measured in each of the substrate, which exist in substrate regions different for each substrate. Then, the measurement results of the line widths at the measurement points of the substrates are combined, so that the line widths at 36 measurement points are finally detected. According to the present invention, the measurements of product substrates can be performed without decreasing the throughput of processing of the product substrates.

Abstract: A thermal plate of a heating unit is divided into a plurality of thermal plate regions, and a temperature can be set for each of the thermal plate regions. A temperature correction value for adjusting a temperature within the thermal plate can be set for each of the thermal plate regions of the thermal plate. The line widths within the substrate which has been subjected to a photolithography process are measured, and an in-plane tendency of the measured line widths is decomposed into a plurality of in-plane tendency components using a Zernike polynomial. From the calculated plurality of in-plane tendency components, in-plane tendency components improvable by changing the temperature correction values are extracted and added together to calculate an improvable in-plane tendency of the measured line widths within the substrate.

Abstract: 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.

A temperature correction value for adjusting a temperature within the thermal plate can be set for each of the thermal plate regions of the thermal plate. The line widths within the substrate which has been subjected to a photolithography process are measured, and, from an in-plane tendency of the measured line widths, an in-plane tendency improvable by temperature correction and an unimprovable in-plane tendency are calculated using a Zernike polynomial. An average remaining tendency of the improvable in-plane tendency after improvement obtained in advance is added to the unimprovable in-plane tendency to estimate an in-plane tendency of the line widths within the substrate after change of temperature setting.
