An electron microscope includes a stage on which a sample is capable of being placed, a beam generator, a detector, a display, and a controller. The beam generator emits a charged particle beam with which the sample is irradiated. The detector detects a secondary electron or an electron generated from the sample by irradiation with the charged particle beam. The display displays an image of the sample based on a signal from the detector. The controller executes a first irradiation process of specifying a position of a hole bottom by scanning the sample with the charged particle beam when capturing an image of the hole bottom of a hole provided in the sample, and executes a second irradiation process of imaging a shape of the hole bottom by irradiating the hole bottom with the charged particle beam via the hole.

A structure for grounding an extreme ultraviolet mask (EUV mask) is provided to discharge the EUV mask during the inspection by an electron beam inspection tool. The structure for grounding an EUV mask includes at least one grounding pin to contact conductive areas on the EUV mask, wherein the EUV mask may have further conductive layer on sidewalls or/and back side.
