Abstract

PURPOSE: To obtain an inspection assignment area capable of the assigning inspection area with ease irrespective of the shapes of the inspection area by indicating the inspection area with an area mask.
CONSTITUTION: An inspection area mask 13 is so fixed to an XY stage 12 that it moves together with the XY stage 12 mounted to the material 11 to be inspected. A transmission type area mask is used as the inspection area mask 13 and an inspection area detecting system constituted by a light source 14 and a photo detector 15 positioned above and below with the inspection area mask 13 in-between is used. The inspection area mask 13 is then mounted on the XY stage 12, and depending upon whether the light from the light source is masked by the inspection area mask 13 or not, the inspection area is displayed by a black and white pattern, thus from the presence or not of the light from the area mask, the inspection area may be discriminated.
