    Abstract: A scanning electron microscope (SEM) with a swing objective lens (SOL) reduces the off-aberrations to enhance the image resolution, and extends the e-beam scanning angle. The scanning electron microscope comprises a charged particle source, an accelerating electrode, and a swing objective lens system including a pre-deflection unit, a swing deflection unit and an objective lens, all of them are rotationally symmetric with respect to an optical axis. The upper inner-face of the swing deflection unit is tilted an angle θ to the outer of the SEM and its lower inner-face is parallel to the optical axis. A distribution for a first and second focusing field of the swing objective lens is provided to limit the off-aberrations and can be performed by a single swing deflection unit. Preferably, the two focusing fields are overlapped by each other at least 80 percent.

    Abstract: An electron microscope has a large depth of focus in comparison with an optical microscope. Thus, information is superimposed on one image in the direction of depth. Therefore, it is necessary to accurately specify the three-dimensional position and density of a structure in a specimen so as to observe the three-dimensional structure of the interior of the specimen by using the electron microscope. Furthermore, a specimen that is observed with the optical microscope on a slide glass is not put into a TEM device of the related art. Thus, performing three-dimensional internal structure observation with the electron microscope on a location that is observed with the optical microscope requires very cumbersome preparation of the specimen. By controlling a vector parameter that defines the interrelationship between a primary charged particle beam and the specimen and by irradiation with the primary charged particle beam with a plurality of different vector parameters, images of transmitted charged particles of the specimen that correspond to each of the vector parameters are obtained. Irradiation with the primary charged particle beam is performed on the specimen that is arranged either directly or through a predetermined member on a detector which detects charged particles transmitted through or scattered by the interior of the specimen.

    Abstract: An ion implantation apparatus includes a beam scanning unit and a beam parallelizing unit arranged downstream thereof. The beam scanning unit has a scan origin in a central part of the scanning unit on a central axis of an incident ion beam. The beam parallelizing unit has a focal point of a parallelizing lens at the scan origin. The ion implantation apparatus is configured such that a focal position of the incident beam into the scanning unit is located upstream of the scan origin along the central axis of the incident beam. The focal position of the incident beam into the scanning unit is adjusted to be at a position upstream of the scan origin along the central axis of the incident beam such that a divergence phenomenon caused by the space charge effect in an exiting ion beam from the parallelizing unit is compensated.
