  • Patent number: 7819159
    Abstract: A bonding apparatus, suitable for accurately bonding large substrates for a liquid crystal display, includes Z-axis drive mechanisms, and upper and lower chambers. The Z-axis drive mechanisms for moving an upper frame vertically are disposed at four corners of a mount. The upper chamber is supported by the upper frame and has an upper table inside. The lower chamber has a lower table inside and is supported on the mount. The upper and lower chambers are united through a seal ring to define a vacuum chamber. Moving the upper frame moves the upper chamber vertically to open or close the vacuum chamber. The lower table is supported via a free joint stage between the plurality of support legs and the table, and is moved horizontally by a side thrust mechanism disposed outside of the vacuum chamber.

  • Publication number: 20090202138
    Abstract: The present invention provides an inspection apparatus having a high throughput and high sensitivity with respect to a number of various manufacturing processes and defects of interest in inspection of a specimen such as a semiconductor wafer on which a pattern is formed. The apparatus illuminates with light the specimen having the pattern formed thereon, forms an image of the specimen on an image sensor through a reflective optics, and determines the existence/nonexistence of a defect. The reflective optics has a conjugate pair of Fourier transform optics. An aberration of the reflective optics is corrected off-axis. The reflective optics has a field of view in non-straight-line slit form on the specimen surface. Also, the optics is of a reflection type, includes a conjugate pair of Fourier transform optics and has a field of view in non-straight-line slit form. An optimum wavelength band is selected according to the specimen (FIG. 1).

  • Publication number: 20090161943
    Abstract: The invention is directed to find a false defect from defect candidates and obtain a threshold with which the false defect can be eliminated by the smallest number of review times. Defect candidates are reviewed and selected as a defect or a false defect. By deleting a defect candidate having a characteristic quantity equal to or less than that of the false defect from a map or displaying it in another sign, the false defect can be determined visually. Since the defect candidate having the characteristic quantity equal to or less than that of the selected false defect is deleted from the map or displayed in another sign, the defect candidates unnecessary to set a threshold are not reviewed. The number of defect candidates to be reviewed can be largely reduced as compared with that in the conventional technique. Further, by repeating the above work, the threshold is automatically calculated, and an inspection result map with the threshold is displayed, so that a re-inspection is unnecessary.

  • Patent number: 7535562
    Abstract: In the conventional methods for enhancing defect detection sensitivity by improving the resolving power, if a microscopic pattern, which is a high spatial-frequency structure as is the case with a microscopic defect, has become the brightest portion, the gray-scale contrast of the microscopic defect will be enhanced. At the same time, however, the gray-scale contrast of the microscopic pattern will also be enhanced simultaneously. Consequently, there has existed a problem that it is impossible to enhance the microscopic-defect detection sensitivity further than that. In the present invention, an aperture stop which is divided into a plurality of small apertures is located on an illumination pupil plane. Then, light-shield/light-transmission for each small aperture is controlled independently of each other. This control allows an inspection-target object to be illuminated at only an incident angle at which the gray-scale contrast of the microscopic defect will be emphasized more sharply.

  • Patent number: 7513824
    Abstract: A game device displays on a display monitor scenes of a vehicle moving in response to manipulations by the player. The display monitor further displays a plurality of goal determining elements. A goal point and a time limit to reach the goal point are set when one of the goal determining elements is picked up. Time is counted from when the goal point and the time limit are set. The game device determines an amount of time for the vehicle to reach the goal point and a score that the player has achieved.
