Abstract: A method for manufacturing a semiconductor device. A photolithographic coating, including a first film, a photolithographic film, and a second film, is formed on the to-be-connected structure. Refractive indexes of the first film and the second film are smaller than 1, so that the photolithographic coating forms an optical structure with a high reflection coefficient.

A pattern of the mask is simultaneously imaged to the photolithographic film. That is, both the to-be-connected structure and the pattern of the mask are imaged to a target region of the photolithographic film, and the target region corresponds to the to-be-connected structure.
