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 18):
The combined magnetic deflection unit and electrostatic deflection unit according to  claim 17  being configured for use in a multi-beam charged particle column, comprising:\n one or more emitters which are arranged for creating multiple primary charged particle beams directed along trajectories towards the surface of the sample arranged on a sample holder, \n an objective lens unit for focusing said multiple primary charged particle beams on said sample, \n a detector system for detecting signal charged particles created upon incidence of the primary charged particle beams on said sample, and \n wherein the combined magnetic deflection unit and electrostatic deflection unit is arranged between the detector system and the sample holder, wherein each strip of said plurality of strips is located next to 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, wherein the plurality of strips of a magnetic or ferromagnetic material is configured to establish a magnetic field having field lines which cross a trajectory of the primary charged particle beams at an angle which is larger than 0 degrees.
