Abstract:
A charged particle beam system is disclosed, comprising: a charged particle beam generator for generating a beam of charged particles; a charged particle optical column arranged in a vacuum chamber, wherein the charged particle optical column is arranged for projecting the beam of charged particles onto a target, and wherein the charged particle optical column comprises a charged particle optical element for influencing the beam of charged particles; a source for providing a cleaning agent; a conduit connected to the source and arranged for introducing the cleaning agent towards the charged particle optical element; wherein the charged particle optical element comprises:  a charged particle transmitting aperture for transmitting and/or influencing the beam of charged particles, and at least one vent hole for providing a flow path between a first side and a second side of the charged particle optical element, wherein the vent hole has a cross section which is larger than a cross section of the charged particle transmitting aperture.  Further, a method for preventing or removing contamination in the charged particle transmitting apertures is disclosed, comprising the step of introducing the cleaning agent while the beam generator is active.

Claim (Index 24):
A method for preventing or removing contamination of a charged particle transmitting aperture in the charged particle beam system according to  claim 1 , the method comprising the steps of:\n providing the beam generator module above the second aperture element or the module comprising said second aperture element; and providing the restriction element between the beam generator module and said second aperture element or a downstream module comprising said second aperture element to restrict a flow path between the beam generator module and said second aperture element or a downstream module comprising said second aperture element.
