Abstract:
A multi-beam charged particle column for inspecting a surface of a sample includes a source for creating multiple primary charged particle beams which are directed towards the sample, an objective lens unit for focusing the primary charged particle beams on the sample, a detector for detecting signal charged particles from the sample, and a magnetic deflection unit arranged between the detector and the sample. The magnetic deflection unit includes a plurality of strips of a magnetic or ferromagnetic material. At least two strips of the plurality of strips are located at opposite sides of a trajectory of a primary charged particle beam and within a distance equal to a pitch of the trajectories of the primary charged particle beams at the magnetic deflection unit. The strips are configured to establish a magnetic field having field lines substantially perpendicular to the trajectories of the primary charged particle beams.

Claim (Index 17):
A combined magnetic deflection unit and electrostatic deflection unit,\n wherein the magnetic deflection unit comprises a plurality of strips of a magnetic or ferromagnetic material, wherein the strips of said plurality of strips are arranged spaced apart and in a common plane, wherein the plurality of strips of a magnetic or ferromagnetic material is configured to establish a magnetic field in between the strips having field lines which extend substantially parallel to said common plane, wherein the electrostatic deflection unit comprises a series of electrode strips of a conductive material arranged spaced apart and in a second common plane, which the series of electrode strips are configured to establish an electrostatic field in between said electrode strips having field lines which extend substantially parallel to said second common plane and substantially perpendicular to the field lines of the magnetic field, and wherein the first common plane and the second common plane are arranged spaced apart.
