Abstract:
1. An inspection device comprising: an electron beam source; an objective lens which focuses an electron beam emitted from the electron beam source on a sample; a sample stage on which the sample is placed, the sample stage including a conductive plate for placing the sample thereon, and a plate made of an insulating material; a plurality of probes each disposed on a respective probe stage, the plurality of probes configured to come into contact with an upper surface the sample facing the electron beam source; a switch which selects one from: a side for grounding the conductive plate, and a side for grounding the conductive plate through a resistance, wherein: the switch is turned to the side for grounding the conductive plate through the resistance when a wire of the sample stage comes into contact with the conductive plate, the probe stages are positioned at sides of the sample stage, and the probe stages and sample stage are configured to move in directions of a plurality of axes.
