  • Publication number: 20200264507
    Abstract: The present invention provides an imprint method that performs a process of forming a pattern of an imprint material on a substrate using a mold, for each of a plurality of shot regions on the substrate, the process including: dispensing the imprint material onto the substrate; moving, to below the mold, the substrate on which the imprint material is dispensed; and supplying, in a moving path of the substrate in the moving, a first gas that promotes filling of the imprint material into a pattern of the mold, wherein in a case where a target shot region to be subjected to the process meets a predetermined condition, supplying a second gas having a lower oxygen concentration than air onto the substrate is additionally executed for the target shot region after the supplying the first gas.

  • Publication number: 20190317398
    Abstract: Provided is an apparatus which is advantageous in view of reduction of consumption of a replacement gas. An apparatus for forming a pattern on a substrate using a mold includes a gas supply unit, a positioning unit and a controller. The controller controls a gas supply unit and a positioning unit and, causes second contact between a second shot region different from a first shot region and the mold after first contact between a first shot region having a material supplied thereon among the plurality of shot regions and the mold and controls the positioning unit so that a second gap which is the distance at the time of changing a relative position between the mold and the substrate in a surface direction from the first shot region to the second shot region is shorter than a first gap which is the distance at the time of gas supply.

  • Patent number: 10095117
    Abstract: An imprint apparatus molds an uncured resin on a substrate and cures the resin to form a pattern of the cured resin on the substrate. The apparatus includes a mold holding unit that holds the mold, a substrate holding unit that holds the substrate, a deforming unit that deforms the mold held by the mold holding unit into a convex shape toward the substrate, a driving unit that changes an attitude of the mold or the substrate during a releasing operation in which the mold deformed into the convex shape is released from the resin to thereby make the position of a contact region at which the mold is brought into contact with the resin movable, a measuring unit that acquires image information indicating a state of the contact region, and a control unit configured to control the operation of the driving unit based on the image information.

  • Publication number: 20170210036
    Abstract: A mold replicating method for replicating a master mold (mold) by forming a pattern of the master mold on a substrate, the method comprising: obtaining information related to a shape difference between a pattern region of the master mold and a pattern region of the substrate; and deforming a relative shape of the pattern region of the master mold and the pattern region of the substrate by applying heat based on the information. The master mold (mold) and the substrate differ in an amount of deformation with respect to the heat applied.
