20100225906 | Surface inspection apparatus and surface inspection method - A surface inspection apparatus and a surface inspection method aim to securely deal with finer repetition pitch without shortening the wavelength of illumination light. To this end, the apparatus includes a unit illuminating repetitive pattern(s) formed on the substrate surface to be inspected with linearly polarized light, a unit setting to an oblique angle an angle between the direction of an intersecting line of a vibration plane of the linearly polarized light on the substrate surface and the repetition direction of repetitive pattern(s), a unit extracting a polarized light component perpendicular to the vibration plane of the linearly polarized light, from light having been emitted from the repetitive pattern(s) in a specular direction, and a unit detecting a defect of the repetitive pattern(s) according to the light intensity of the polarized light component. | 2010-09-09 |
20100225907 | SURFACE INSPECTION WITH VARIABLE DIGITAL FILTERING - A semiconductor wafer, which is an inspection object, is stuck by vacuum on a chuck and this chuck is mounted on an inspection object movement stage consisting of a rotational stage and a translational stage, located on a Z-stage. The rotational stage provides a rotational movement and the translational stage provides a translational movement. And when a foreign particle or a defect on an inspection object surface is detected, the parameter of digital filtering is dynamically changed during inspection, and the foreign particle or the defect is differentiated using the result after removing a low frequency fluctuation component to be a noise component. | 2010-09-09 |
