Patent ID: 7018932

Claim:
A method for manufacturing a semiconductor device, the method comprising: forming a photosensitive film on a main surface of a semiconductor substrate; carrying the semiconductor substrate on which the photosensitive film is formed, to an exposure device provided with a mask in which an on-mask inspection mark and an on-mask device pattern are formed to form an inspection mark and a device pattern, respectively, on the photosensitive film; selectively exposing the photosensitive film to light to transfer the on-mask inspection mark to the photosensitive film to form a latent image of the inspection mark on the photosensitive film; heating at least that area of the photosensitive film in which the latent image of the inspection mark is formed, to relieve the image of the inspection mark; measuring the relieved image of the inspection mark; changing set values for the exposure device used for the selective exposure, on the basis of result of the measurement so that exposure conditions conform to the set values; exposing the photosensitive film on the basis of the changed set values to transfer the on-mask device pattern to the photosensitive film to form a latent image of the device pattern on the photosensitive film; heating an entire surface of the photosensitive film; and developing the photosensitive film.
