    • PROBLEM TO BE SOLVED: To provide a data management device capable of shortening the inspection time even when design data of a semiconductor circuit are used.
      SOLUTION: The data management device 100 is connected to an appearance inspecting apparatus 104a for detecting a defect candidate on a wafer and acquiring the coordinates of the defect candidate, a design data server 102 for storing the design data of the semiconductor circuit, and the defect reviewing apparatus 108a for imaging the defect candidate on the basis of the coordinates to acquire a defect candidate image, comparing the defect candidate image with a reference image without a defect and specifying a defect. The data management device comprises a first detection part 1 for detecting that the appearance inspecting apparatus 104a is executing the acquisition of the coordinates, a storage control part 2 for making write of the coordinates from the appearance inspecting apparatus 104a to a storage part 2a be started by the detection, and a defect peripheral design data acquisition part 3 for acquiring defect peripheral design data capable of generating the reference image so as to include the coordinates from a part of the design data. The storage control part 2 associates the defect peripheral design data with the coordinates and stores them in the storage part 2a.

    • PROBLEM TO BE SOLVED: To solve the problems wherein, when an illuminance distribution in an illumination spot by an actual illumination optical system is not a Gaussian distribution, each accuracy of particle size calculation of a foreign matter or a defect to be detected and coordinate position detection on the inspection object surface is lowered. SOLUTION: In this device equipped with an illumination spot illuminance distribution data table for storing the illuminance distribution in the illumination spot, the coordinate position and the particle size calculation of the foreign matter or the defect are performed based on detection light intensity data from the foreign matter or the defect and the illumination spot illuminance distribution data table. Hereby, even if the illuminance distribution in the illumination spot by the actual illumination optical system is not necessarily the Gaussian distribution, each accuracy of the particle size calculation of the foreign matter or the defect to be detected and the coordinate position on the inspection object surface can be improved.
