  • Patent number: 11249394
    Abstract: An imprint method for forming a pattern of an imprint material on a substrate-side pattern region of a substrate by using a mold. The method includes deforming a partial region of the substrate, the partial region corresponding to the substrate-side pattern region, by irradiating the substrate with light that has passed through the mold and has a first wavelength different from light having a second wavelength that is used for curing the imprint material, and curing the imprint material by irradiating the light having the second wavelength in a state in which the substrate-side pattern region is deformed and the mold is contacted with the imprint material. The step of deforming includes forming an uneven temperature distribution on the substrate-side pattern region by irradiation of the light having the first wavelength with an uneven illumination distribution.

  • Patent number: 10663858
    Abstract: An imprint apparatus that forms a pattern of an imprint material on a substrate-side pattern region of a substrate by using a mold. The imprint apparatus includes a light irradiation unit configured to irradiate the imprint material with light having a first wavelength for curing, and a heating unit configured to heat a partial region of the substrate, the partial region corresponding to the substrate-side pattern region, by irradiating the substrate with light that has passed through the mold and has a second wavelength different from the light having the first wavelength. The heating unit is configured to heat the partial region to deform the substrate-side pattern region by forming an uneven temperature distribution on the substrate-side pattern region by irradiation of the light having the second wavelength with an uneven illumination distribution.
