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. The photolithographic coating is exposed to a light having a first wavelength, to image the to-be-connected structure to a first region of the photolithographic film. The photolithographic coating is exposed to a light having a second wavelength through a mask, to image the mask to a second region of the photolithographic film. A region in which the first region and the second region overlap serves as a connection region corresponding to the to-be-connected structure, and thereby self-alignment between a layer of the to-be-connected structure and a layer where a contact hole is arranged is implemented.

Method for manufacturing semiconductor device

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. The photolithographic coating is exposed to a light having a target wavelength through a mask. The to-be-connected structure is reflected in the photolithographic coating, and hence serves as another mask and is imaged to the photolithographic film. 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.
