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 6):
The multi-beam charged particle column according to  claim 1 , wherein the plurality of strips of the magnetic deflection unit are arranged in a common plane, wherein said strips comprises a ferromagnetic material, and wherein at least one of said strips is provided with at least two electric wires which extend in a direction substantially parallel to the common plane, wherein the two electric wires are arranged in a plane substantially perpendicular to the common plane, and wherein the magnetic deflection unit is configured to provide an electrical current to the two electric wires wherein the electrical current is configured to flow through the two electric wires in opposite direction.
