More Information
Summary:A scanning electron microscope is disclosed. The primary electron beam is radiated on a reticle (specimen), and an observation image of the reticle is obtained using the electrons secondarily released. The microscope comprises a lamp for radiating the vacuum ultraviolet light having the wavelength of not more than 172 nm on the reticle in the atmosphere, a radiation chamber for hermetically sealing the reticle so that the vacuum ultraviolet light can be radiated on the reticle, and a specimen holder for holding the reticle in the radiation chamber and capable of adjusting the distance between the lamp and the reticle.
