Summary:A method for manufacturing an extreme ultraviolet (EUV) pellicle structure may include preparing a pellicle membrane that includes an intermediate layer structure in which EUV transmission layers and heat dissipation layers are alternately stacked, a first thin layer disposed on a top surface of the intermediate layer structure, and a second thin layer disposed on a bottom surface of the intermediate layer structure and having a heat emissivity lower than that of the first thin layer, and disposing a cooling structure for absorbing heat from the pellicle membrane on an edge sidewall of the pellicle membrane at which the heat dissipation layers are exposed.
