Abstract

PURPOSE:To effectively correct the defective improper part in a metal mask by forming a correcting metal pattern only on the defective improper part and its periphery of a metal pattern. CONSTITUTION:This method includes the steps of covering a metal mask 1 having a defective improper part 2 with a transparent conductive film 5, covering the film 5 with a positive transparent photosensitive material film 6 and removing the spot exposed part 7 of the positive transparent photosensitive material film surface on the defective improper part and its periphery. Subsequently, correcting metal pattern 8 is formed on the exposed film 5, and the film 5 and the film 6 except the necessary part are isolated from the metal mask.
