    摘要: A system and method for determining measurement results of a dark-field inspection apparatus up to a microscopic area. A dark-field inspection apparatus is calibrated using a reference wafer having microroughness of an irregular asperity pattern accurately formed on a surface, and the microroughness of the surface having an ensured microroughness degree. This microroughness is measured by using an AFM, and an expected haze value is obtained based on the measured value. Then, haze of the surface of the reference wafer is measured by the dark-field inspection apparatus to be inspected to obtain an actually-measured haze value, and a difference between the expected haze value and the actually-measured haze value is obtained. Based on this difference, a haze measurement parameter of the dark-field inspection apparatus is adjusted so that the actually-measured haze value and the expected haze value match each other.

    摘要: 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.
