  • Publication number: 20180370091
    Abstract: The present invention provides an imprint apparatus which forms a pattern of an imprint material onto a substrate by using a mold, the apparatus including a control unit configured to provide a user interface for displaying a first map indicating a supply position of the imprint material to be supplied onto the substrate, an adjustment window for adjusting a value of an apparatus parameter which is set in the imprint apparatus and used to change a supply position of the imprint material, and a second map indicating a supply position of the imprint material after adjustment of the value of the apparatus parameter.

  • Publication number: 20170212419
    Abstract: An imprinting method is capable of strictly interpolating application distribution of uncured resin material being applied to a substrate for each shot and interpolating application distribution of uncured resin material for each shot while reducing workload in a generation step. The imprinting apparatus includes a mold; a mold driving unit; a dispenser that applies uncured resin material to the substrate; a light source that cures uncured resin material as a pattern; a dispenser control unit that controls the dispenser by generating the application distribution of the uncured resin material to the resin pattern for each of a plurality of shots; and a main control unit that interpolates application distribution of uncured resin material, which has been generated by the dispenser control unit, using shot layout information of relative position among positions of a plurality of shots, the dispenser, and the light source with respect to the substrate, as variables.

  • Patent number: 9651860
    Abstract: Provided is an imprinting method that is capable of strictly performing the interpolation of the application distribution of an uncured resin material to be applied to a substrate for each shot as well as efficiently performing the reinterpolation of the application distribution of the uncured resin material for each shot while reducing the workload in a generation step.

  • Publication number: 20160167261
    Abstract: An object of the present disclosure is to provide an imprinting apparatus capable of detecting a surface state of a substrate with accuracy even when the surface state of the substrate changes. An imprinting apparatus of the present disclosure is one for contacting an imprint material on a substrate with a mold, and forming a pattern of the imprint material on the substrate. The imprinting apparatus includes a detector configured to irradiate the substrate with light, optically detect reflected light from the substrate to detect a state of the imprint material on the substrate, and switch a detection condition during an imprinting process.

  • Publication number: 20160158978
    Abstract: The present invention provides an imprint apparatus that performs imprint processing of forming a pattern of an imprint material on a substrate using a mold, the apparatus including an image sensing unit configured to sense at least one of the mold and the substrate and obtain an image, and a determination unit configured to determine normality/abnormality of the imprint processing, wherein the imprint processing includes a first step of supplying the imprint material onto the substrate, and a second step of bringing the mold and the imprint material on the substrate into contact with each other, and the determination unit changes a reference of determination of the normality/abnormality of the imprint processing for each step of the imprint processing and determines the normality/abnormality of the imprint processing based on the image sensed by the image sensing unit.

  • Publication number: 20160046065
    Abstract: The present invention provides an imprint apparatus which forms a relief pattern in an imprint material on a substrate using a mold, the apparatus including a curing unit configured to cure the imprint material, a moving unit configured to relatively move the mold and the substrate, a detection unit configured to detect a pattern of light reflected by the mold and light reflected by the substrate, and a processing unit configured to obtain information on a separation state of the mold and the cured imprint material on the substrate based on the pattern detected by the detection unit while separating the mold from the imprint material by widening, using the moving unit, an interval between the mold and the substrate.
