  • Molding apparatus, molding method, and manufacturing method of article
    Patent number: 11584048
    Abstract: An apparatus according to the present exemplary embodiment is an apparatus that forms a composition on a substrate using a mold. The apparatus includes a gas supply unit that supplies gas to a periphery of a space sandwiched between the mold and the substrate, a deforming mechanism that deforms the mold, and a control unit that, in a state in which the gas supply unit increases a density of the gas in the periphery of the space sandwiched between the mold and the substrate, after the deforming mechanism deforms the mold in a concave shape with respect to the substrate and releases the mold from the deformation, brings the mold into contact with the composition on the substrate.
    Type: Grant

  • Imprint apparatus and article manufacturing method
    Patent number: 10488752
    Abstract: An imprint apparatus includes: a dispenser configured to dispense an imprint material to the imprint region; and a controller configured to control the imprint process so that a pattern is formed in a first imprint region, located upstream of a second imprint region with respect to a gas flow between the dispenser and the substrate, earlier than in the second imprint region.
