Abstract:
1. A measuring method, implemented by a control unit that has been programmed with instructions that cause the control unit to function as a substrate measuring system, of measuring processing states of a plurality of substrates, the substrates having been successively transferred and subjected to processing, said method comprising the steps of: dividing a plurality of measurement points within each of the plurality of substrates into a plurality of regions in advance; measuring the processing states at only one of the plurality of regions for each of the plurality of substrates, such that a different measured region is measured on a different substrate of the plurality of substrates and a number of the plurality of regions corresponds to a number of the plurality of substrates; and combining measurement results at the measurement points of the plurality of substrates so there is no overlapping portion and the measurement results over the entire surface of one substrate is obtained, wherein the plurality of substrates are a plurality of physical wafers.
