Abstract:
Disclosed is a charged particle optical apparatus. The charged particle optical apparatus has a liner electrode in a first vacuum zone. The liner electrode is used to generate an electrostatic objective lens field. The apparatus has a second electrode which surrounds at least a section of the primary particle beam path. The section extends in the first vacuum zone and downstream of the liner electrode. A third electrode is provided having a differential pressure aperture through which the particle beam path exits from the first vacuum zone. A particle detector is configured for detecting emitted particles, which are emitted from the object and which pass through the differential pressure aperture of the third electrode. The liner electrode, the second and third electrodes are operable at different potentials relative to each other.

Claim (Index 5):
A method of operating a charged particle optical apparatus, the charged particle optical apparatus comprising:\n a particle optical arrangement, configured to define a particle beam path for inspecting an object; a specimen chamber configured to accommodate the object in a pressure-controlled interior of the specimen chamber during the inspection of the object; and a differential pressure module having at least one differential pressure aperture; wherein the method comprises: acquiring a first image with the differential pressure module positioned in a non-operating position in which the differential pressure module is outside the primary particle beam path; positioning the differential pressure aperture within the pressure-controlled interior of the specimen chamber from the non-operating position into an operating position; wherein when the differential pressure aperture is in the operating position, the primary particle beam path enters into the pressure-controlled interior of the specimen chamber by passing through the differential pressure aperture; acquiring a second image with the differential pressure module positioned in the operating position; wherein at least a portion of the first image and at least a portion of the second image represent a same object portion of the object.
