Abstract
PURPOSE: To eliminate or amend an abnormal spot pattern on a mask or a wafer in a short time by photoetching based on the step and repeat method, in which a reticle for amendment is used.
CONSTITUTION: After measuring the size and position of an abnormal spot pattern on a master mask, positive resist is coated on the whole surface of the mask. A reticle 6 which is made by forming an exposure window 4 on a metal thin film layer 5 is used. The exposure window 4 is bigger than an abnormal pattern 3 and has such a size as not cause any influence on the mask pattern 1. For poor mask, by referring to the position of the abnormal pattern, the step and repeat method is used for exposure and developing etching to eliminate the abnormal pattern. As the result, the time required for exposure is shorten because the step and repeat method is employed.
