ABSTRACT:
The method for repairing the pattern is to repair the lacking portion of the pattern included in the X-ray exposure mask with the WF.sub.6 gas being filled in the vicinity thereof, wherein the focused ion beam irradiates the defect portion, whereby the WF.sub.6 gas is decomposed to form a tungsten thin film so as to at least fill the lacking portion. On this occasion, the focused ion beam is successively applied so that it is always in contact with the edge of the tungsten thin film constituting the pattern.
