    Abstract: The present invention relates to atom probe pulse energy. One aspect of the invention is directed toward a method that includes establishing a data relationship between pulse energy and bias energy for a target evaporation rate. In selected embodiments, establishing a data relationship can include determining an equivalent pulse fraction for a selected pulse energy and bias energy combination based on a local change in bias energy compared to a local change in pulse energy associated with the selected pulse energy and bias energy combination. Another aspect of the invention is directed toward a method that includes determining an equivalent pulse fraction for a first bias energy and pulse energy combination and/or a second bias energy and pulse energy combination based on the difference between the first bias energy and the second bias energy compared to the difference between the first pulse energy and the second pulse energy.

    Abstract: The invention relates to an emission electron microscope, comprising an objective lens, an imaging system with at least one lens and a stigmator. The invention is characterised in that said microscope comprises a second, independent imaging system (K2), parallel to the first imaging system (K1) and two electron detector devices (25) and (27), by means of which two independent images are recorded: a real image and an image of the angle distribution of the electrons as a result of electronically switching the potentials of the deflector elements (13) and (17). Both identical deflector elements comprise pairs of spherical and concentric electrodes and are electron-optically separated from each other (13a), (13b) and (17a), (17b) by double the focal length thereof and turn the electron beam through an angle corresponding to ( beta ) and (- beta ), which leads to a parallel shift of the electron beam. The electrode (13b) contains a passage (13c), which allows the electron drift along the electron-optical main axis (29a), whilst the deflection is switched off. Said emission electron microscope also comprises an electron source (8), arranged close to the electron-optical axis (29) of the objective lens, which emits primary electrons along the electron-optical axis (28) at an angle ( alpha ) to the electron-optical axis (29) of the objective lens, a contrast diaphragm system (4a) in a plane correlated to the focal plane of the objective and an image diaphragm system (11), in one of the image planes of the system.

    Abstract: An apparatus and method for inspecting a surface of a sample (S), particularly but not limited to a semiconductor device, using an electron beam presented. The technique is called Secondary Electron Emission Microscopy (SEEM), and has significant advantages over both Scanning Electron Microscopy (SEM) and Low Energy Electron Microscopy (LEEM) techniques. In particular, the SEEM technique utilizes a beam of relatively high-energy primary electrons (11) having a beam width approximate for parallel, multi-pixel imaging. The electron energy is near a charge-stable condition to achieve faster imaging than was previously attainable with SEM, and charge neutrality unattainable with LEEM.
