  • Patent number: 8761518
    Abstract: According to one embodiment, a pattern inspection apparatus includes a first inspection data creation section, a first delay section, a first recognition section, a first extraction section, a first and a second level difference calculation section, a first and a second determination section, and a first logic OR calculation section. The first extraction section extracts data of a sub-resolution pattern from the first inspection data and the first delay data. The first and second level difference calculation section calculate differences between an average output level of a surrounding region for a target pixel of the extracted data from the first inspection data or the first delay data and an output level of the extracted data. The first and second determination sections determine presence or absence of a defect. The first logic OR calculation section calculates logic OR of determination results of the first and second determination sections.

  • Patent number: 8054437
    Abstract: A plurality of panels (40) are cut from a large substrate (mother substrate) including a lower large substrate (41A) and an upper large substrate (42A). For each panel (40), a frame-shaped seal (47) and a connection electrode forming section (C) are formed in the large substrate. Since the left side (47c) of the frame of a panel (40) is close to the right side (47b) of the frame of the left-adjacent panel, these sides of the seals are formed from a sealing material containing a lower density of spacers. Since the upper side (47a) of the frame of a panel (40) is separated from the lower side (47d) of the frame of the upper adjacent panel (40) by an extension (C?) for the connection electrodes, these seal members are formed from a sealing material containing a higher density of spacers.
