  • Publication number: 20240127417
    Abstract: The present disclosure proposes a system for detecting a foreign material adhering to or a scratch formed on a bevel at an edge of a semiconductor wafer in order to detect the foreign material or defect on the bevel without using a reference image and including a learning device (905) that outputs information on the foreign material adhering to or the scratch formed on the bevel as a learning result, in which the learning device performs learning in advance by using image data acquired by an image acquisition tool and the information on the foreign material or the scratch on the bevel included in the image data, and the foreign material or the scratch is detected by inputting the image data obtained by the image acquisition tool to the learning device (refer to FIG. 9).

  • Publication number: 20240127421
    Abstract: An object of the present disclosure is to provide a defect classification device capable of easily grasping an appropriate recipe update timing of an imaging device when classification accuracy for classifying defects existing on a semiconductor wafer is decreased. The defect classification device according to the present disclosure calculates classification accuracy by further acquiring a result of a manual classification for defects spanning a plurality of classification spaces as a result of an automatic classification, and comparing the result of the automatic classification with the result of the manual classification (see FIG. 5).

  • Publication number: 20040002149
    Abstract: The present invention provides recombinant gene vectors and nucleic acid constructs which are capable of decreasing, reducing or suppressing the transcription/translation of LIP (transcription inhibitor protein), and in some examples, without affecting the transcription/translation of LAP (transcription activator). Such vectors and constructs are used in methods for increasing the ratio of LAP to LIP activity in a cell and for treating and/or ameliorating the symptoms of a disease or condition associated with the ratio of LAP to LIP. The present invention also provides methods for screening for agents that are capable of modifying the ratio of LAP to LIP activity in a cell or individual.

  • Publication number: 20020051760
    Abstract: A method for screening a substance having promoting activity on hair growth, which comprises the steps of bringing hair follicles in telogen into contact with a test substance, and judging that the substance tested is positive when the hair follicles in telogen are led to in anagen by the substance tested, wherein the judgment is carried out by detecting expression of Hacl-1 in the hair follicles.
