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 1):
A multi-beam charged particle column for inspecting a surface of a sample, which 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, an objective lens unit for focusing said multiple primary charged particle beams on said sample, a detector system for detecting signal charged particles created upon incidence of the primary charged particle beams on said sample, a magnetic deflection unit arranged between the detector system and the sample holder, wherein the magnetic deflection unit comprises a plurality of strips of a magnetic or ferromagnetic material, wherein at least one strip of said plurality of strips is located next to a trajectory of a primary charged particle beam and wherein said at least one strip is arranged 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 for establishing a magnetic field having field lines which cross the trajectories of the primary charged particle beams at an angle which is larger than 0 degrees, an electrostatic deflection member which is configured for creating an electrostatic field acting at least on the primary charged particle beams, wherein the electrostatic deflection member is configured to provide an electrostatic field in a direction at least substantially perpendicular to the magnetic field of the magnetic deflection unit, and wherein the magnetic deflection unit and the electrostatic deflection member are arranged spaced apart in a direction parallel to the trajectories of the primary charged particle beams.
