  • Patent number: 10184790
    Abstract: The presently disclosed subject matter provides a pattern measurement method and device for achieving highly accurate measurement in the depth direction of a pattern. The method involves a focused ion beam irradiated to form an inclined surface in a sample area; a field of view of a SEM set to include the boundary between the inclined surface and a sample surface; and an image of the field of view obtained on the basis of a detection signal. Such an acquired image is used to specify a first position, the boundary between inclined surface and non-inclined surface, and a second position, the position of a desired deep hole or deep groove positioned within the inclined surface. The pattern dimension in a height direction is determined on the basis of the distance in the sample surface direction between the first position and second position and the angle of the inclined surface.

  • Patent number: 10180317
    Abstract: In order to provide a pattern-measuring device and a computer program that quantitatively evaluate the effects brought about by the presence of pattern deformations in a circuit, this invention proposes a pattern-measuring device that measures first distances between first edges in pattern data being measured and second edges that correspond to said first edges in a benchmark pattern that corresponds to the pattern being measured. Said pattern-measuring device computes a score for the first edges or the pattern being measured on the basis of the first distances and second distances between the first edges and/or the second edges and third edges that are adjacent to but different from the first and second edges.

  • Patent number: 10168345
    Abstract: An automatic analysis apparatus capable of improving detection sensitivity is provided. An optimum photometer between a light-scattering photometer and an absorptiometer based on a concentration range may be decided. A standard solution is measured multiple times at a normal calibration and a calibration curve is created. Calibration curves are individually created for an absorptiometer and a light-scattering photometer from the minimum and maximum measured values of the concentrations of each standard solution. The upper and lower limits of a standard solution concentration are computed from the minimum/maximum calibration curves. Sensitivity may be computed by using calibration parameters. Whether to use a concentration by absorption or a concentration by scattered light is decided based on the computed sensitivity. The computed sensitivities are compared between the concentration by absorption and the concentration by scattered light, and the use of the concentration of a higher sensitivity is decided.

  • Patent number: 10168286
    Abstract: In a scheme for analyzing low magnification defect images and determining whether or not a defect detection method using cell comparison is applicable, if a defect detection method using cell comparison cannot be applied and the proportion transitioning to a defect detection method using die comparison increases, throughput may decrease even more than starting out with defect detection by a defect detection method using die comparison. The purpose of present invention is to carry out high precision defect detection with a stable throughput. In the present invention, the defect detection processing mode applied for detecting defects from the defect image is determined using a reference image, and defects are detected from the defect image by the defect detection processing mode that has been determined.

  • Patent number: 10168208
    Abstract: A signal detected by a photomultiplier tube is pre-amplified and converted into a digital signal. A time average value of signal components, each of which has a voltage lower than a predetermined base threshold value, is calculated as a base voltage. A signal that has been subjected to base correction processing is subjected to threshold value processing and to base correction processing in a non-incident state in which light is not incident on the photomultiplier tube. An output signal thereof is subjected to dark current calculation processing; and a light emission signal amount is calculated by subtracting, from the signal component of the detection light obtained by the threshold value processing, a time average value of the signal components of the dark current. As the result, discriminating the dark current pulse from floor noises enhances the accuracy of the base voltage, and thus the accuracy of light detection.

    Abstract: A two-dimensional code is attached to a location of a reagent storage unit which is visually recognizable from the outside, and a coordinate position of the two-dimensional code in a coordinate system of the two-dimensional code and coordinate information of an installation position of a reagent bottle are held. After that, an image of the two-dimensional code is captured by a portable terminal so that a coordinate system of an image capture unit of the portable terminal is converted into the coordinate system of the two-dimensional code using AR technology. The coordinate information of the installation position of the reagent bottle in the coordinate system of the two-dimensional code is regarded as positional coordinates in the captured image on the basis of the conversion, thereby ascertaining the position of the reagent bottle on the captured image and displaying the ascertained position on a display unit.

  • Patent number: 10157724
    Abstract: In a scanning electron microscope, an atmospheric pressure space having a specimen arranged therein and a vacuum space arranged on a charged particle optical system side are isolated from each other using an isolation film that transmits charged particle beams. The scanning electron microscope has an electron optical lens barrel, a chassis, and an isolation film. The electron optical lens barrel radiates a primary electron beam onto a specimen. The chassis is directly bonded to the inside of the electron optical lens barrel and has an inside that turns into a lower vacuum state than the inside of the electron optical lens barrel at least during the radiation of the primary electron beam. The isolation film isolates a space in an atmospheric pressure atmosphere having a specimen mounted therein and the inside of the chassis in a lower vacuum state, and transmits the primary charged particle beam.
