Abstract

PURPOSE:To manufacture a high-accuracy photomask in a high yield by selectively applying radiation to a transparent substrate until the substrate screens ultraviolet and visible rays to correct or remove pinholes, etc. in a metal mask such as a photomask for an integrated circuit. CONSTITUTION:On glass substrate 1 transparent to ultraviolet and visible rays wiring or an element pattern is formed as thin layer 2 of a metal such as Cr or Ni or a metal oxide such as chromium oxide. When pinhole 3, dot 4, unsatisfactory form portion 5, etc. are present in the pattern, in order to correct pinhole 3 an area slightly larger than pinhole 3 is irradiated with radiation 7 such as gamma-Co rays while regulating the area with aperture 6 to change part 8 of transparent substrate 1 in quality so that it screens ultraviolet and visible rays. Aperture 6 is of radiation screening substance such as Au. A pattern face may directly be formed on substrate 1 by applying radiation 7 besides the correction. Thus, a high-accuracy photomask is easily manufactured in a high yield.
