Abstract:
1. An inspection apparatus, comprising: a charged particle beam source; a stage for mounting a specimen; a lens for converging the charged particle beam on to the specimen; a deflector for deflecting the charged particle beam; a detector for detecting charged particle beam emission from the specimen; a display apparatus for displaying a specimen image in accordance with a signal from the detector, wherein the display apparatus further comprises: a memory for storing information of relative relation between a coordinate of a position on the specimen obtained by carrying out an alignment between the specimen image and a layout image of a wiring pattern of the specimen, and a coordinate of the layout image; and a processing apparatus for converting a shift amount of the specimen image by the deflector of the charged particle beam into a shift amount of the layout image in accordance with the information stored in the memory, wherein the processing apparatus displays the specimen image and the layout image of the wiring pattern of the specimen in coordinate on the display apparatus, and when the specimen image is shifted by the amount of the specimen shift, the layout image is displayed by shifting by the amount of the layout shift.
