The present disclosure is related to a Schottky thermal field (TFE) source for emitting an electron beam. Electron optics can adjust a shape of the electron beam before the electron beam impacts a scintillator screen. Thereafter, the scintillator screen generates an emission image in the form of light. An emission image can be adjusted and captured by a camera sensor in a camera at a desired magnification to create a final image of the Schottky TFE source's tip. The final image can be displayed and analyzed to for defects.

Provided is a technique capable of achieving both throughput and robustness for a function of adjusting brightness (B) and contrast (C) of a captured image in a charged particle beam device. The charged particle beam device includes a computer system having a function (ABCC function) of adjusting the B and the C of an image obtained by imaging a sample. The computer system determines whether adjustment is necessary based on a result obtained by evaluating a first image obtained by imaging an imaging target of the sample (step S2), executes, when the adjustment is necessary based on a result of the determination, the adjustment on a second image of the imaging target to set an adjusted B value and an adjusted C value (step S4), and captures a third image of the imaging target based on the adjusted setting values to generate an image for observation (step S5).

To provide a charged particle beam device including a booster electrode and an object lens that generates a magnetic field in a vicinity of a sample, and capable of preventing ion discharge, an insulator is disposed between a magnetic field lens and the booster electrode. A tip of the insulator protrudes to a tip side of an upper magnetic path from a tip of a lower magnetic path of the magnetic field lens. The tip on a lower side of the insulator is above the lower magnetic path, and a non-magnetic metal electrode is embedded between the upper magnetic path and the lower magnetic path.
