发明名称 Charged particle microscope providing depth-resolved imagery
摘要 A method of examining a sample using a charged-particle microscope, comprising mounting the sample on a sample holder; using a particle-optical column to direct at least one beam of particulate radiation onto a surface S of the sample, thereby producing an interaction that causes emitted radiation to emanate from the sample; using a detector arrangement to detect at least a portion of said emitted radiation, the method of which comprises embodying the detector arrangement to detect electrons in the emitted radiation; recording an output On of said detector arrangement as a function of kinetic energy En of said electrons, thus compiling a measurement set M={(On, En)} for a plurality of values of En; using computer processing apparatus to automatically deconvolve the measurement set M and spatially resolve it into a result set R={(Vk, Lk)}, in which a spatial variable V demonstrates a value Vk at an associated discrete depth level Lk referenced to the surface S, whereby n and k are members of an integer sequence, and spatial variable V represents a physical property of the sample as a function of position in its bulk.
