    Abstract: A scanning transmission electron microscope equipped with an aberration corrector is capable of automatically aligning the position of a convergence aperture with the center of an optical axis irrespective of skill and experience of an operator. The scanning transmission electron microscope system includes an electron source; a condenser lens configured to converge an electron beam emitted from the electron source; a deflector configured to cause the electron beam to perform scanning on a sample; an aberration correction device configured to correct an aberration of the electron beam; a convergence aperture configured to determine a convergent angle of the electron beam; and a detector configured to detect electrons passing through or diffracted by the sample. The system acquires information on contrast of a Ronchigram formed by the electron beam passing through the sample, and determines a position of the convergence aperture on the basis of the information.

    Abstract: Transmission microscopy imaging systems include a mask and/or other modulator situated to encode image beams, e.g., by deflecting the image beam with respect to the mask and/or sensor. The beam is modulated/masked either before or after transmission through a sample to induce a spatially and/or temporally encoded signal by modifying any of the beam/image components including the phase/coherence, intensity, or position of the beam at the sensor. For example, a mask can be placed/translated through the beam so that several masked beams are received by a sensor during a single sensor integration time. Images associated with multiple mask displacements are then used to reconstruct a video sequence using a compressive sensing method. Another example of masked modulation involves a mechanism for phase-retrieval, whereby the beam is modulated by a set of different masks in the image plane and each masked image is recorded in the diffraction plane.

    Abstract: In one embodiment, an aperture member producing method includes applying a charged particle beam to a plurality of chip areas on a first substrate while changing a writing condition to write a first pattern corresponding to an aperture opening, processing the first substrate based on the written first pattern to form a second pattern, cutting out a chip area provided with the second pattern having desired accuracy from the first substrate to produce a template, allowing the template to come into contact with a resist overlying a front surface of a second substrate, separating the template from the hardened resist to pattern the resist with a transfer pattern, processing the second substrate using the transfer pattern as a mask to form a first recess, and etching a rear surface of the second substrate to form a second recess communicating with the first recess.

    Abstract: A focused ion beam apparatus includes an ion gun unit having an emitter tip, a gas supply unit that supplies gas to the tip, and an ion source gas supply source. An extracting electrode ionizes the gas adsorbed onto the surface of the tip and extracts ions by applying a voltage between the extracting electrode and the tip. A cathode electrode accelerates the ions toward a sample. An aperture member has an opening that passes therethrough a part of the ion beam ejected from the ion gun unit, and a lens system focuses the ion beam onto the sample.
