Patent ID: 7462829

Claim:
A substrate inspection apparatus comprising: an electron beam irradiation device which emits an electron beam and causes the electron beam to irradiate a substrate to be inspected as a primary beam; an electron beam detector which detects at least one of a secondary electron, a reflected electron and a backscattered electron that are generated from the substrate that has been irradiated by the electron beam, and which outputs a signal that forms a one-dimensional or two-dimensional image of a surface of the substrate; a mapping projection optical system which causes imaging of at least one of the secondary electron, the reflected electron and the backscattered electron on said electron beam detector as a secondary beam; and an electromagnetic wave irradiation device which provides a location on the surface of the substrate at which the secondary beam is generated, with energy to thereby migrate a local charge within the substrate by generating an electromagnetic wave and causing the electromagnetic wave to irradiate the location.
