  • Patent number: 11604415
    Abstract: A substrate processing method includes: forming a coating film on a substrate by supplying a resist liquid which is photosensitive to extreme ultraviolet (EUV) light to a surface of the substrate; forming a semi-solidified film by volatilizing a solvent contained in the coating film without heating the solvent; irradiating the semi-solidified film with EUV light thereby exposing the semi-solidified film with EUV light; and supplying a developer to the substrate after the exposure of the semi-solidified film.

  • Publication number: 20230042982
    Abstract: A technique for suppressing a metal component from remaining at a bottom of a mask pattern when the mask pattern is formed using a metal-containing resist film. A developable anti reflection film 103 is previously formed below a resist film 104. Further, after exposing and developing the wafer W, TMAH is supplied to the wafer W to remove a surface of the antireflection film 103 facing a bottom of the recess pattern 110 of the resist film 104. Therefore, the metal component 105 can be suppressed from remaining at the bottom of the recess pattern 110. Therefore, when the SiO2 film 102 is subsequently etched using the pattern of the resist film 104, the etching is not hindered, so that defects such as bridges can be suppressed.
