  • Patent number: 7822574
    Abstract: In the present invention, substrates in a plurality of lots are successively processed in a coating and developing treatment system, and line width measurement is performed for some of substrates of the substrate which have been through processing in each lot. The line width measurement of two successive lots is performed such that the last line width measurement in the previous lot of the two successive lots has been completed at the time of completion of processing of a substrate which is first subjected to the line width measurement in the subsequent lot. According to the present invention, the measurement of product substrates can be performed without decreasing the throughput of the product substrates.

  • Publication number: 20090181316
    Abstract: In a pattern measuring unit installed in a coating and developing treatment system, the height of a pattern formed on a substrate is measured using the Scatterometry method. Based on the measured height of the pattern, an appropriate number of rotations of the substrate during application of a coating solution is calculated, so that the rotation of the substrate during the application is controlled by the calculated number of rotations of the substrate. Since the number of rotations of the substrate when the coating solution is applied to the substrate is controlled, it is unnecessary to stop the system which performs photolithography processing on the substrate, resulting in improved productivity of the substrate.

  • Publication number: 20080257495
    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.

  • Publication number: 20080142508
    Abstract: In the present invention, 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, 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.
