摘要:
A scanning charged particle microscope is offered which can selectively detect and image electrons. The scanning charged particle microscope (100) has: a source (1) of a charged particle beam (E1); an objective lens (6) for bringing the charged particle beam (E1) emitted from the source (1) into focus at a sample (S); a scanning deflector (4) for scanning the focused charged particle beam (E1) over the sample (S); a sorting portion (10) for sorting out electrons emitted at given emission angles from electrons released from the sample (S) in response to irradiation of the sample (S) by the charged particle beam (E1); an electron deflector (20) for producing a deflecting field to deflect the electrons (E2) sorted out according to their energy; a detection portion (30) for detecting the electrons (E2) deflected by the electron deflector (20); and an image creating portion (44) for creating an image, based on the results of the detection performed by the detection portion (30).
