Patent ID: 7214937

Claim:
An electron microscope for observing a surface or inside of a semiconductor wafer or a mask for exposing a semiconductor pattern for faults and/or foreign objects, comprising: a function of loading measurement data of coordinates of said faults and/or foreign objects which were observed by another wafer or mask inspecting apparatus, moving a field of view of the electron microscope to an area of coordinates of said fault and/or foreign object, and simultaneously displaying said coordinates of said faults and/or objects which were obtained by observing said semiconductor wafer or said mask with said another wafer or mask inspecting apparatus, an electron microscope image of said field of view of the electron microscope, a vicinity area of said field of view of the electron microscope, showing said fault positions and sizes according to the coordinates and the sizes of said fault and/or foreign object observed by said another wafer or mask inspecting apparatus, a function of moving said field of view of the electron microscope when the fault is not found to a position which is pointed by a pointer on a display, and a function of magnifying said vicinity area after moving said field of view of the electron microscope, wherein said field of view and the magnification of said vicinity area are automatically shrunk when said field of view of the electron microscope is not found in the vicinity area after the movement of the field of view of the electron microscope or said field of view and the magnification of the vicinity area are automatically enlarged when said field of view of the electron microscope is in the vicinity area after the movement of the field of view of the electron microscope.
