Apparatus and method for examining specimen with a charged particle beam

摘要

An apparatus for examining a specimen with a beam of charged particles. The apparatus comprises a particle source for providing a beam of charged particles and an optical device for directing said beam of charged particles onto said specimen to be examined. Furthermore, a gas supply provides inert gas to the area of incidence of said beam of charged particles onto said specimen. The specimen can be loaded into a vacuum chamber. <IMAGE>
