    摘要: An analysis method by which a surface impurity in a very small region can be specified, wherein an electron beam is accelerated with an acceleration voltage and irradiated upon a very small region of a specimen and a mass spectrometry of neutral surface impurity molecules desorbed from the very small region is performed. The acceleration voltage for accelerating the electron beam is set to a voltage with which desorption of the neutral surface impurity molecules by an electron stimulated desorption (ESD) effect occurs.

    摘要: A focused ion beam system capable of acquiring surface structure information, internal structure information, and internal composition information about a sample simultaneously from the same field of view of the sample. A method of sample preparation and observation employs such focused ion beam system to accurately set a sample processing position based on information about the structure and composition of the sample acquired from multiple directions of the sample, and to process and observe the sample. The system includes, in order to acquire the sample structure and composition information simultaneously, a secondary electron detector, a transmission electron detector, and an energy dispersive X-ray spectroscope or an electron energy loss spectroscope, and employs a stub having the sample rotating and tilting function. The method includes a marking process.

    摘要: A standard sample for transmission electron microscopy (TEM) elemental mapping and a TEM elemental mapping method using the same are provided. The standard sample includes a substrate; a first crystalline thin film containing heavy atoms formed on the substrate; a first amorphous thin film having oxides or nitrides containing light atoms and having a thickness of 1–5 nm or 6–10 nm formed on the first crystalline thin film; a second crystalline thin film containing heavy atoms formed on the first amorphous thin film. The standard sample can be used to correct TEM, EDS and EELS mapping results of a multi-layered nanometer-sized thin film and to optimize mapping conditions.

    摘要: A method of calculating an electronic state of a material by using a calculation device, wherein the calculation device sets a set containing, as elements, a plurality of operation models, where each of operation models provides an approximate solution to the electronic state of the material, determines an optimized operation model that are close in distance in a space formed by the set while defining a direction in which the calculated self-consistent solutions of the effective Hamiltonian of an electron system continuously change, evaluates a variational energy of the electron system by the self-consistent solution, updates the operation model so that the evaluated variational energy approaches an energy of an exact solution to be calculated and further, so that the variational energy forms a monotonically decreasing convex function, and calculates the exact solution of the electronic state from one or a plurality of variational energy series.

At least one planar filter (10) is provided for receiving the charged particles having the substantially parallel trajectories and for filtering the charged particles in accordance with their respective energies. A second non-imaging electrostatic lens (11) receives the energy filtered charged particles and selectively modifies their trajectories as a function of their energies.
