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.
