Zusammenfassung:An object is to prevent a breakage of a membrane probe and a wafer to be tested in a probe testing using a membrane probe with styluses formed by a manufacturing technology for a semiconductor integrated circuit device. Measures are: obtaining an image of a region PCA within the surface of a wafer including a region OGA pressed by a pressing member, at the center of which a chip just after probe-tested is located, by an imaging means such as a camera; comparing an image of a normal chip obtained in advance and an image of all the chips within the region PCA; and judging thereby whether an abnormal shape is caused or not in all the chips within the region PCA.
