Abstract: PURPOSE: A method for manufacturing a diaphragm for an exposure equipment is provided to maintain the resolution and improve the light transmitting degree. CONSTITUTION: A first resist pattern is formed in a selected area on a substrate. A first optical shielding material is formed on the substrate, which includes the first resist pattern. After the first resist pattern is removed, a second resist is formed on the structure. Then, the central portion of the second resist is removed. After a second optical shielding material is formed on the structure, the second resist is removed.
