An object of the present invention is to provide methods and equipment capable of providing highly accurate matching using a template including multiple patterns even when the shapes of some patterns of the template are different from corresponding ones of a SEM image, and when the template and the SEM image have a magnification error. Proposed, as a technique for achieving the object, is a method for performing matching by selectively using some of multiple patterns provided in a predetermined region of design data, and equipment for implementing the method. Moreover, proposed, as another technique for achieving the object, is a method for performing first matching by using multiple patterns provided in a predetermined region of design data and thereafter performing second matching by using some of the multiple patterns provided in the predetermined region, and equipment for implementing the method.
