Abstract

PURPOSE: To improve accuracy when making a pattern of photoresist film on the surface of a substrate which has a recess, by coating the resist film on the entire surface, performing a restricted quantity of selective exposure to light to cause insufficient cross-linking reaction, removing the unexposed part of the film and effecting heat treatment.
CONSTITUTION: To make a pattern of photoresist film on an SiO2 film 1 having a step, a resist film 2 is rotatively coated and baked first. A photomask 3 is placed on the resist film 2 so that a dark part 4 of chromium oxide on the bottom of the mask corresponds to a recess. Ultraviolet rays 5 are irradiated upon the side of the mask opposite the dark part 4 so that the irradiated quantity of the rays is about a half of a conventional irradiated quantity. The mask 3 is removed. A developer is sprayed on the entire surface. Only the film part 2b corresponding to the dark part 4 in he recess is completely removed so that an opening 8 is provided and the other film part 2a remains at the peripheral section of the recess and a projecting portion. Since the film part 2a is swollen due to the insufficient irradiated quantity and pinholes 7 or the like are produced, heat treatment is effected to cause thermal polymerization. The pinholes 7 are thus filled so that a desired pattern 2d is provided.
