  • Patent number: 10249034
    Abstract: A method of adjusting a sensitivity parameter value for substrate defect inspection used in a substrate defect inspection apparatus compares, for each pixel value of a selected virtual inspection substrate, using reference pixel data to be used after adjustment, the deviation amount from an allowable range corresponding to the position thereof and the sensitivity parameter value before the adjustment when each pixel value is deviated from the allowable range, and updates the deviation amount as a new sensitivity parameter value when the deviation amount exceeds the sensitivity parameter value and a difference between the deviation amount and the sensitivity parameter value is equal to or less than a threshold value.

  • Patent number: 9766543
    Abstract: In one embodiment, a liquid treatment method includes (A) imaging a discharging port part of the liquid nozzle each time the discharging process is performed to one substrate, and acquiring, from images thus obtained, size data on foreign matter possibly present at the discharging port part; and (B) based on a history of the size data arranged in chronological order, judging whether an abnormality in substrate-processing has occurred. In the item (B), if the number of continuous acquisition, indicating how many times the size data not smaller than a first threshold value has been acquired continuously, exceeds a predetermined value, then judging that an abnormality in substrate-processing has occurred.

  • Patent number: 6984137
    Abstract: The invention provides an electrical connector assembly that is constituted by a first connector and a second connector, each of the first and second connectors having signal contacts disposed in two rows, a grounding member disposed between the rows of signal contacts and a housing that holds the signal contacts and the grounding member and being engaged with each other, and an electrical connector that constitutes the electrical connector assembly. The electrical connector and electrical connector assembly increase the reliability of a grounding path, require only a small number of component parts and are suitable for high-speed signal transmission. A first grounding plate and a second grounding plate that constitute the grounding member are disposed in the immediate vicinity of rows of signal contacts that are disposed in two rows and the housing has a through opening. Therefore, a connection section that constitutes the grounding member can be visually checked.
