    摘要: A deflection system is presented for use in a lens arrangement of a charged particle beam column for inspecting a sample. The system comprises a magnetic deflector operable to create a magnetic field, and a pole piece assembly at least partly accommodated within the magnetic field. The pole piece assembly has a portion made of a soft magnetic material and is formed with an opening for a charged particle beam propagation therethrough. The deflection system allows for conducting the magnetic field created by the magnetic deflector through the pole piece assembly towards the opening in the pole piece assembly. This enables to increase the magnetic field value in the vicinity of the sample at the optical axis of the lens arrangement at a given electric current through the excitation coils of the magnetic deflector, without a need to increase a working distance.

    摘要: An improved objective lens for a charged particle beam device is constituted by, among other things, a magnetic lens that creates a first magnetic field for focussing the charged particle beam onto the specimen. Furthermore, a deflector is integrated into the magnetic lens by providing at least one additional coil arrangement that creates a second magnetic field used to deflect the charged particle beam. Thereby, the second magnetic field is guided through at least one of the pole pieces of the magnetic lens. The present invention also provides an improved column for a charged particle beam device including the improved objective lens.
