  • Publication number: 20170069458
    Abstract: The objective of the present invention is to simply perform image observation through transmitted charged particles. A sample irradiated by a charged particle beam is disposed directly or via a predetermined member on a light-emitting element (23) whereinto charged particles that have traversed or scattered inside the sample enter, causing a light to be emitted therefrom, which is collected and detected efficiently using a light transmission means (203) to generate a transmission charged particle image of the sample.

  • Patent number: 9208994
    Abstract: The present invention provides an electron beam apparatus comprising a means for visualizing an axial displacement of a retarding electric field, and a means for adjusting axial displacement. The axial displacement visualizing means includes a reflective plate (6), and an optical system (2, 3) for converging a secondary electron beam (9) on the reflective plate (6), and the axial displacement adjusting means includes an incline rotation mechanism (8) for a sample stage (5). With this configuration, in electron beam apparatuses such as SEM and the like, such problems as visual field displacement caused by displacement of the axial symmetry of the electric field between an objective lens (3) and a sample (4) and inability to measure secondary electrons and reflected electrons that provide desired information can be eliminated.
