Zusammenfassung:PROBLEM TO BE SOLVED: To easily and rapidly correct a circuit on a mask pattern. SOLUTION: The method for correcting a mask pattern circuit to correct a mask pattern circuit is carried out by forming a predetermined thin film by using a focused ion beam and a film forming gas on an aperture pattern circuit formed on a mask to shut the aperture pattern circuit. Then, a mask material at a desired position on the mask is etched by using a focused ion beam and an etching gas to form a predetermined aperture pattern circuit on the mask.
