  • Patent number: 7220969
    Abstract: Embodiments include determining whether defects exist in an extreme ultraviolet (EUV) light mask blank. Incident EUV light scattered or diffused by abnormalities in the layers of the mask blank may be measured, normalized, and compared to threshold values to determine if and where a defect exists. Normalizing may be performed by dividing a light intensity value for a pixel by the average of light intensity values for one or more rings of surrounding pixels. A defect may be determined by considering whether the normalized intensity value for a pixel is greater than a pixel threshold to identify the pixel is a candidate for a location with a defect; and by determining whether the sum of normalized light intensity values for a block of pixels including the pixel satisfies a pixel block threshold to determine whether the block scatters or diffuses a critical amount of light to identify a defect.

  • Publication number: 20070052914
    Abstract: With substrates to be bonded together becoming larger, there are problems in that a bonding apparatus needs to be built larger to maintain accuracy of products and operation of such a bonding apparatus becomes more complicated. A bonding apparatus includes Z-axis drive mechanisms, an upper chamber, and a lower chamber. The Z-axis drive mechanisms for moving an upper frame vertically are disposed at four corners of a mount. The upper chamber is suspended from the upper frame and has an upper table inside. The lower chamber has a lower table inside. The lower table is supported on the mount via a plurality of support legs. The upper chamber and the lower chamber are united together through a seal ring to define a vacuum chamber. The upper table is coupled to the upper frame and moved by the Z-axis drive mechanisms via the upper frame. Moving the upper frame moves the upper chamber vertically to open or close the vacuum chamber.

  • Publication number: 20060262297
    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.
