摘要: A method for evaluating a specimen includes positioning a detector in an inserted position in which a first distance between a tip of the detector and a plane extending along a surface of the specimen is less than a distance between the plane and a tip of charged particle beam optics. While maintaining the detector at the inserted position, the surface of the specimen is scanned by a primary beam that exits from the tip of the charged particle beam optics. The detector detects x-ray photons and/or charged particles emitted or reflected from the specimen as a result of scanning the specimen with the primary beam. After completion of the scanning, the detector is positioned at a retracted position in which a second distance between the tip of the detector and the plane exceeds a distance between the tip of the charged particle beam optics and the plane.

摘要: A detecting method and a detecting equipment therefor are provided. The detecting method includes: inspecting whether a display panel has a defective position; after acquiring the defective position of the display panel by the inspecting, using a first focused ion beam generated by a first ion overhaul apparatus to cut the defective position of the display panel, so as to strip a defect at the defective position and observe morphology of defect; using a repair apparatus to perform a repair treatment on the defective position after the defect is stripped. An inspection apparatus for the inspecting of the defective position, the first ion overhaul apparatus and the repair apparatus are sequentially installed on the same production line.
