  • Patent number: 8084194
    Abstract: A method of substrate edge treatment includes forming a processing target film on a treatment target substrate, applying an energy line to a predetermined position on the processing target film to form a latent image on the processing target film, heating the treatment target substrate in which the latent image is formed on the processing target film, developing the processing target film after the heating, inspecting whether a residue is present at an edge of the treatment target substrate after the developing, and cleaning an end of the treatment target substrate to remove the residue at the edge of the treatment target substrate determined to be defective in the inspecting.

  • Publication number: 20110229826
    Abstract: This invention discloses a method to form a resist pattern on a to-be-processed substrate by immersion exposure. A resist film is formed on the central portion of the upper surface of the to-be-processed substrate, on a bevel portion of the upper surface, which is obtained by chamfering the peripheral portion of the to-be-processed substrate, and on the end portion of the to-be-processed substrate. Pattern exposure for forming the latent image of a desired pattern on the resist film is executed while a liquid whose refractive index is higher than that of air exists between the resist film and a constituent element of a projection optical system of an exposure apparatus, which is nearest to the to-be-processed substrate. The resist film formed on the end portion of the to-be-processed substrate is removed by supplying a rinse solution to the end portion of the to-be-processed substrate after executing pattern exposure.

  • Patent number: 7709383
    Abstract: A film forming method comprising forming a liquid coating film on a substrate by supplying a liquid containing a coating type thin film forming substance and a solvent onto the substrate, substantially converging a variation in film thickness of the coating film, making the coating film stand by in an atmosphere including moisture under a predetermined condition after the substantial-convergence, the predetermined condition being such that a product of a time for which the coating film is exposed to the atmosphere and a water content per unit volume in an atmosphere in the vicinity of a surface of the coating film is made to be greater than or equal to a predetermined value, and forming a solid thin film on the substrate after the stand-by, the thin film being formed by carrying out an elimination of the solvent in the coating film and heat treatment for generating an irreversible reaction to the coating type thin film forming substance in the coating film.
