    摘要: A method for performing milling and imaging in a focused ion beam (FIB) system employing an inductively-coupled plasma ion source, wherein two sets of FIB system operating parameters are utilized: a first set representing optimized parameters for operating the FIB system in a milling mode, and a second set representing optimized parameters for operating in an imaging mode. These operating parameters may comprise the gas pressure in the ICP source, the RF power to the ICP source, the ion extraction voltage, and in some embodiments, various parameters within the FIB system ion column, including lens voltages and the beam-defining aperture diameter. An optimized milling process provides a maximum milling rate for bulk (low spatial resolution) rapid material removal from the surface of a substrate. An optimized imaging process provides minimized material removal and higher spatial resolutions for improved imaging of the substrate area being milled.

    摘要: Disclosed is an operation for an optical system which achieves observation of focused ion beam processing equivalent to that in a case wherein a sample stage is tilted mechanically. In a focused ion beam optical system, an aperture, a tilting deflector, a beam scanner, and an objective lens are controlled so as to irradiate an ion beam tilted to the optical axis of the optical system, thereby achieving thin film processing and a cross section processing without accompanying adjustment and operation for a sample stage. The thin film processing and the cross section processing with a focused ion beam can be automated, and yield can be improved. For example, by applying the present invention to a cross section monitor to detect an end point, the cross section processing can be easily automated.

To achieve the object, a scanning electron microscope including a plurality of apertures through which an electron beam can pass and a mechanism for switching the apertures for the electron beam, and a method for controlling sample charging by switching the apertures are proposed. The plurality of apertures are at least two apertures. Portions respectively having different secondary electron emission efficiencies are provided on peripheral portions of the at least two apertures on a side opposed to the sample. The quantity of electrons generated by collision of electrons emitted from the sample can be controlled by switching the apertures.
