  • Patent number: 11681216
    Abstract: An apparatus forms a pattern of an imprint material by curing the imprint material in a state in which the imprint material on a pattern formation region of a member, where a pattern is to be formed, is in contact with a pattern region of a mold. The apparatus includes a dispenser for placing the imprint material on the pattern formation region of the member and a non-pattern formation region of the member, outside the pattern formation region, a detector for detecting the non-pattern formation region in a state in which the imprint material has been placed on the pattern formation region and the non-pattern formation region by the dispenser, and a controller for performing processing for determining an abnormality in the dispenser based on a detection result of the non-pattern formation region by the detector.

  • Publication number: 20230057796
    Abstract: A control apparatus for performing position control of a moving object is provided. The apparatus includes a feedforward controller configured to perform feedforward control by giving a feedforward manipulated variable to the moving object. In a case that a duration of the feedforward control exceeds a predetermined time, the feedforward controller continues the feedforward control using a feedforward manipulated variable obtained based on a feedforward manipulated variable used in a predetermined section including an end of the predetermined time.

  • Patent number: 10751930
    Abstract: The present invention an imprint apparatus which performs an imprint process of forming a pattern in an imprint material on a substrate using a mold, the apparatus including an image capturing unit configured to obtain an image by capturing the substrate, and a processing unit configured to perform detection processing of detecting a foreign particle present between the mold and the substrate, wherein the processing unit performs the detection processing by comparing, with a reference image, an image obtained by the image capturing unit in a state in which the mold and the imprint material on the substrate are in contact with each other, and when the image includes a region outside the substrate, the region outside the substrate is excluded from a target of the detection processing.

  • Patent number: 10372034
    Abstract: An imprint apparatus for forming a pattern of an imprint material on a substrate using a mold includes a heating unit, a generation unit, and a measurement unit. The heating unit irradiates a region to be processed on the substrate with light to heat the region to be processed. The generation unit generates irradiation amount distribution data, which indicates an irradiation amount distribution of light with which the heating unit is to irradiate the region to be processed. The measurement unit measures information about absorption of the light by the region to be processed. The generation unit generates the irradiation amount distribution data by correcting, using a result of measurement by the measurement unit, temporary irradiation amount distribution data temporarily generated based on a shape of the region to be processed taken before the region to be processed is heated by the heating unit.

  • Patent number: 5946332
    Abstract: A connection monitoring system is provided for monitoring a connection between separated oscillator and power units not only in an initial time period just after the connector has been connected to the interface but also in a time period when the laser is in serve for allowing a long life time of the laser by preventing the laser oscillator unit from an excess large load even if a connector is incompletely connected to an interface of the electric device or if a connector pin is incompletely in contact with the interface. A thermal switch recognition system is further provided for recognizing excess temperature increase of the laser tube which can ascertain which thermal switch has been opened for allowing a long life-time of the laser tube by recognizing a position where an excess temperature increase appears.
