  • Patent number: 10437153
    Abstract: A substrate having a surface on which a resist film is formed and that has undergone pattern exposure processing and development processing is conveyed into a chamber and held by a holding plate. The surface of the substrate W held by the holding plate is irradiated with flash light emitted from flash lamps. The spectral distribution of the flash light has a peak in a wavelength range of 200 nm to 300 nm. The spectral distribution of the flash light also shows that the relative intensity at a wavelength of 300 nm is 20% or more higher than that at a wavelength of 500 nm. Since the resist film absorbs ultraviolet rays, the resist film can be selectively heated by irradiating the resist film with flash light that includes a large number of wavelength components in the ultraviolet region.
