  • Patent number: 11835854
    Abstract: An imprint device includes a load port for receiving a substrate to be processed, a sensor that acquires information from the substrate about a film on the substrate, and a primer forming unit configured to receive the substrate from the load port. A controller is configured to select primer process conditions corresponding to the film information. The primer forming unit receives primer process conditions from the controller and forms a primer layer on the substrate over the film. The primer layer is formed according to the selected process conditions. An imprinting unit of the imprint device is configured to receive the substrate from the primer forming unit and perform imprint lithography on the substrate.

  • Publication number: 20230194406
    Abstract: A measuring method includes: placing resist 20 on a surface of a test film; pressing a template 30 against the resist 20 placed on the surface of the test film; measuring a size of a void formed in the resist 20 after pressing the template 30 against the resist 20; and determining gas permeability of the test film based on the size of the void.

  • Patent number: 11592741
    Abstract: An imprinting method includes dispensing a first liquid on a first region of a substrate. The first liquid is a photocurable resist precursor. A second liquid is dispensed on a second region of the substrate. The second region is adjacent to and surrounding the first region. The second liquid is non-photocurable as dispensed. The first region is then irradiated with light while a patterned template is being pressed against the first liquid. The light cures the first liquid and forms a resist pattern corresponding to the patterned template. The patterned template and the substrate are then separated from each other. The second liquid is then selectively removed from the substrate while leaving the resist pattern on the substrate.

  • Publication number: 20210041782
    Abstract: An imprint template includes a substrate, a resin film, and a resist-repellant layer. The resin film is provided on the substrate and has an imprint pattern therein. The resist-repellant layer is provided on a surface of the imprint pattern. The resist-repellant layer includes an inorganic element. A method for manufacturing an imprint template includes pressing a substrate against a resin film that has been solidified in a mold having a pattern therein. The resin film having an imprint pattern corresponding to the pattern is thereby transferred to the substrate. A resist-repellant layer is then formed on a surface of the imprint pattern. The resist-repellant layer includes an inorganic element.
