    摘要: A method for evaluating a specimen, the method can include positioning an energy dispersive X-ray (EDX) detector at a first position; scanning a flat surface of the specimen by a charged particle beam that exits from a charged particle beam optics tip and propagates through an aperture of an EDX detector tip; detecting, by the EDX detector, x-ray photons emitted from the flat surface as a result of the scanning of the flat surface with the charged particle beam; after a completion of the scanning of the flat surface, positioning the EDX detector at a second position in which a distance between the EDX detector tip and a plane of the flat surface exceeds a distance between the plane of the flat surface and the charged particle beam optics tip; and wherein a projection of the EDX detector on the plane of the flat surface virtually falls on the flat surface when the EDX detector is positioned at the first position and when the EDX detector is positioned at the second position.

    摘要: A magnetic immersion lens apparatus includes an outer pole piece and an inner pole piece with a gap therebetween. The outer pole piece has an opening that permits energetic particles from a target in front of the immersion lens to pass through the outer pole piece to an external detector. The outer or inner pole piece has one or more notches near the gap.

    摘要: An interface, a scanning electron microscope and a method for observing an object that is positioned in a non-vacuum environment. The method includes: passing at least one electron beam that is generated in a vacuum environment through at least one aperture out of an aperture array and through at least one ultra thin membrane that seals the at least one aperture; wherein the at least one electron beam is directed towards the object; wherein the at least one ultra thin membrane withstands a pressure difference between the vacuum environment and the non-vacuum environment; and detecting particles generated in response to an interaction between the at least one electron beam and the object.

    摘要: A spectrometer having an electron beam generator for generating an electron beam that is directed at a sample. An electron beam positioner directs the electron beam onto a position of the sample, and thereby produces a secondary emitted stream from the sample, where the secondary emitted stream includes at least one of electrons and x-rays. An secondary emitted stream positioner positions the secondary emitted stream onto a detector array, which receives the secondary emitted stream and detects both the amounts and the received positions of the secondary emitted stream. A modulator modulates the electron beam that is directed onto the sample, and thereby sweeps the electron beam between a first position and a second position on the sample. An extractor is in signal communication with both the modulator and the detector array, and extracts a differential signal that represents a difference between the signals that are received from the first position and the signals that are received from the second position.
