  • Patent number: 10094658
    Abstract: To address the problem in which when measuring the overlay of patterns formed on upper and lower layers of a semiconductor pattern by comparing a reference image and measurement image obtained through imaging by an SEM, the contrast of the SEM image of the pattern of the lower layer is low relative to that of the SEM image of the pattern of the upper layer and alignment state verification is difficult even if the reference image and measurement image are superposed on the basis of measurement results, the present invention determines the amount of positional displacement of patterns of an object of overlay measurement from a reference image and measurement image obtained through imaging by an SEM, carries out differential processing on the reference image and measurement image, aligns the reference image and measurement image that have been subjected to differential processing on the basis of the positional displacement amount determined previously, expresses the gradation values of the aligned differential r

  • Patent number: 10094841
    Abstract: A control unit outputs measurement status information including the time up to the completion of creation of the calibration curve for each of the desired measurement items to a display unit. The output/display of the calibration curve data measurement status for each of the items enables the operator to be aware of information about a failure to set a standard solution or to request the setting of the standard solution and to recognize how long he or she will need to wait until the creation of the calibration curve begins. The operator can therefore know what can be done while waiting, thereby improving job efficiency.

  • Patent number: 10096451
    Abstract: The present invention is: a pattern measurement device that, regardless of increased fineness, deviation, or the like of a pattern, accurately and stably performs measurement on the basis of edge identification or pattern or edge judgment; and a computer program. The pattern measurement device classifies pattern sites (G1, G2, G3, G4), which are repeatedly arrayed at a specific interval, in accordance with the position of the pattern sites, and executes a pattern edge type identification, a pattern type identification, or a measurement of the dimensions between predetermined pattern sites on the basis of an association between the classified pattern sites and information pertaining to the pattern edge type or information pertaining to the pattern type. The computer program causes a computer to execute the abovementioned process.

  • Patent number: 10094846
    Abstract: A sample-processing system that improves total system processing efficiency, and reduces a sample-processing time, by establishing a functionally independent relationship between a rack conveyance block with rack supply, conveyance, and recovery functions, and a processing block with sample preprocessing, analysis, and other functions. A buffer unit with random accessibility to multiple racks standing by for processing is combined with each of multiple processing units to form a pair, and the system is constructed to load and unload racks into and from the buffer unit through the rack conveyance block so that one unprocessed rack is loaded into the buffer unit and then upon completion of process steps up to automatic retesting, unloaded from the buffer unit. Functional dependence between any processing unit and a conveyance unit is thus eliminated.

  • Patent number: 10094844
    Abstract: In determining whether a rack inputted to the automatic analyzer by the user is to be transferred to an analysis section or not, samples existing in a route from a buffer to a sample dispensing position in the analysis section are identified, and the number of items in which suction by a nozzle has not been completed in analysis items requested for the samples is managed. When the number of items is reduced to be smaller than a given number, the conveyance of a next rack from the buffer to the analysis section is controlled, thereby limiting the number of analysis items requested for samples in a waiting state for analysis in the analysis section constantly to be smaller than a fixed number. As a result, a period of time until a measurement result of emergency samples is outputted can be reduced even when emergency samples are newly inputted.

  • Patent number: 10090160
    Abstract: There is provided dry etching apparatus including a stage on which a wafer is placed, an antenna electrode, a high frequency power supply, a shower plate, and an RF bias power supply. Further, a bias path controller is provided on the side of the antenna electrode. The bias path controller resonates in series with the static reactance formed by the shower plate with respect to the frequency of the RF bias. Then, the bias path controller changes and grounds the impedance by the variable inductive reactance. With this mechanism, highly uniform etching can be achieved even if a shower plate of quartz is used for corrosive gases.

  • Patent number: 10074506
    Abstract: A conventional method to process a tip fails to designate the dimension of the shape of the end of the tip, and so fails to obtain a tip having any desired diameter. Impurities may be attached to the tip. Based on a correlation between the voltage applied or the time during processing of the end of the tip and the diameter of the tip end, the applied voltage is controlled so as to obtain a desired diameter of the tip end for processing of the tip. This allows a sharpened tip made of a tungsten monocrystal thin wire to be manufactured to have any desired diameter in the range of 0.1 ?m or more and 2.0 ?m or less.

  • Patent number: 10068756
    Abstract: The objective of the presently disclosed subject matter is to provide a mass spectrometer that improves the ionic permeability ratio at the entrance to an ion transport part or the entrance to a mass spectrometry part, and to acquire a high-sensitivity mass spectrum. To reduce the electric-field distortion that is caused by ion loss, electrodes are arranged so that the radius of a circle inscribed within the electrodes of the ion transport part is larger than the radius of a circle inscribed within the electrodes of the mass spectrometry part. The entrance to the electrodes of the mass spectrometry part also can have a tapered, inclined, folded-over, or rounded configuration. Together, these reduce the sharply fluctuating (peak-shaped) distribution of electric potential generated near the entrance to the ion transport part and the entrance to the mass spectrometry part.
