Abstract

A gray-tone mask has a light-shielding portion, a light-transmitting portion, and a gray-tone portion adapted to reduce a transmission amount of exposure light in use of the mask. For manufacturing this gray-tone mask, a method includes a step of preparing a mask blank in which a thin film containing metal and silicon and an inorganic-based etching mask layer each having resistance to etching of the other are formed on a light-transmissive substrate, a step of forming a first resist pattern on the inorganic-based etching mask layer, a step of etching the inorganic-based etching mask layer by using the first resist pattern as a mask and using an etching solution for the inorganic-based etching mask layer, a step of peeling off the first resist pattern remaining after etching the inorganic-based etching mask layer, a step of etching the thin film by using the inorganic-based etching mask layer as a mask and an etching solution for the thin film. The thin film is etched with the first resist pattern peeled off. Thereafter, a second resist pattern is formed on the inorganic-based etching mask layer and the light-transmissive substrate, and the inorganic-based etching mask layer is etched by using the second resist pattern as a mask and then the second resist pattern is peeled off. Thus, the gray-tone portion is formed by the thin film while the light-shielding portion is formed by the inorganic-based etching mask layer and the thin film.
