    摘要: The present invention provides, according to a first aspect, a method for the examination of specimen with a beam of charged particles. The method provides one or more images of the specimen made with different view angles, so that, compared to a single image of the specimen, a lot of additional information about the specimen can be accessed. The different view angles (angles of incidence) are achieved by tilting the beam between the two images and moving the specimen to a new position so that the displacement of the beam caused by the tilting of the beam is compensated. Accordingly, while displaying/recording the second image the beam scans over the same area as it has scanned while displaying/recording the first image.

    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: A method and system are presented for controlling inspection of a sample with a charged particle beam. A certain given voltage is supplied to an anode of the column to provide a required accelerating voltage for a charged particle beam. A certain negative voltage is supplied to the sample selected so as to provide a desirably high effective voltage of the column at said given voltage of the anode. A certain voltage is supplied an electrode of a lens arrangement located closer to the sample, this voltage being selected to satisfy one of the following conditions: the electrode voltage is either equal to or slightly lower than that of the sample; and the electrode voltage is significantly higher than that of the sample.

    摘要: A method and apparatus for use in monitoring a sample with a charged particle beam are presented. A mechanical displacement between a plane defined by the sample's surface and an optical axis defined by a beam directing arrangement is provided so as to orient the sample at a certain non-right angle θ1 with respect to the optical axis. A primary charged particle beam propagating towards the sample is deflected so as to affect the trajectory of the primary charged particle beam to provide a certain non-zero angle θ2 between the primary beam propagation axis and said optical axis.
