  • Publication number: 20240184214
    Abstract: An exposure apparatus includes: a substrate stage onto which a substrate is to be mounted; an exposure unit radiating an exposure light toward the draw-out electrode on at least one semiconductor chip; a pattern determination unit determining an exposure pattern; and a controller controlling the substrate stage and the exposure unit. The pattern determination unit determines a pattern of a relay wiring connecting the draw-out electrode and a predetermined position with respect to the substrate, by using an output from a measurement unit to measure a position of the semiconductor chips on the substrate to obtain a positional deviation. The controller exposes the relay wiring pattern onto an exposure area extending, on the photosensitive layer, in the uniaxial direction by the exposure unit, while moving the substrate from a first-side in the uniaxial direction to a second-side opposite to the first-side in the uniaxial direction by the substrate stage.

  • Patent number: 11988822
    Abstract: The present invention relates to a microscope of which visibility, controllability and operability can be improved. In the microscope, an optical path and optical path of an image forming system are set so as to be perpendicular to each other when viewed from the top. In other words, in this microscope, there exists an ocular optical system that guides light, which propagates the optical path to optical path of the image forming system, to a user. The optical path is formed in a direction perpendicular to a direction of the light from a sample emitted from the ocular optical system to the user.

  • Publication number: 20240157641
    Abstract: Directed energy beam deflections are compensated by mapping pixel coordinates of an image of a patterning field to patterning field spatial coordinates. For example, electron beam scanning is compensated by imaging calibration features defined on a reticle to produce a mapping between pixel and physical coordinates. An electron beam is scanned to produce cathodoluminescence at a plurality of scan locations in a patterning field. With the pixel coordinate mapping, an image of the cathodoluminescence is used to determine compensated scan drive values. Other directed energy beam deflections can be similarly compensated.

  • Patent number: 11980417
    Abstract: In an ophthalmology system, an right-eye imaged image is displayed on a display section for presentation to an observer through an optical unit and a reflection member. A left-eye imaged image is also displayed on a display section for presentation to an observer through an optical unit and a reflection member. A separation between the left and right imaged images is made wider than a spacing between the left and right optical units. This enables image presentation with the optical axes for the observer viewing the images intersecting in front so as to cause a convergence angle to arise.
