Patent ID: 7563561

Claim:
A pattern forming method comprising: forming a photo resist film on a substrate; selectively irradiating the photo resist film with an energy ray to form a desired latent image pattern in each of a plurality of exposure regions of the photo resist film; placing the substrate on a spacer provided on a hot plate, after forming the latent image pattern; heating the photo resist film by using the hot plate; and developing the photo resist film to form a photo resist pattern which corresponds to the latent image pattern, wherein, when the photo resist film is irradiated with the energy ray, an amount of irradiation of the energy ray is set, based on a relationship between an amount of warp of the substrate after forming the photo resist film and an optimal amount of exposure, in such a manner that the amount of irradiation of the energy ray in a first exposure region in which a distance between a back surface of the substrate and an upper surface of the hot plate is long is larger than the amount of irradiation of the energy ray in a second exposure region in which a distance between the back surface of the substrate and the upper surface of the hot plate is short.
