Abstract

PURPOSE:To prevent mold growing during storage in the atmosphere by easy and low cost operation, using a protective film for preventing mold on one face of the glass substrate of a photomask original plate reverse to the light shielding layer of the glass substrate. CONSTITUTION:A protective film for preventing mold is provided on one surface of a glass substrate having a light shielding layer on the other side to form a photomask original plate. As a mold preventing protective film to be applied a film made of silicon dioxide or metallic chromium is recommended. These protective films can be applied by vapor deposition, ion plating, or the like. Before applying the protective film on the reverse face of the glass substrate, preferably a thin film of MgF2, TiO2, CeO2, or the like is attached to it as a reflection preventing film, and on this film the mold preventing film is applied, thus permitting prevention of mold growing, enhancement of optical characteristics of the mask, ad raise of effects of destaticization, etc.
