    摘要: A probe device is fabricated from a glass fiber segment by first isotropically etching only a portion of the diameter of only a bottom region thereof. Next, the bottom region is cleaved, to produce a cleaved bottom endface. Then the cleaved endface and a height of the sidewalls of the bottom region that is less than its total height are coated with a protective masking layer. The fiber segment is immersed in an isotropic etching solution, whereby its diameter is reduced. Finally, the masking layer is stripped off, and the bottom region is etched again until the (maximum) diameter of the cleaved endface is reduced to a desired value.

    摘要: A multiple magnification optical system has a single objective focused upon a specimen at a given working distance. A graded-index lens receives light passing through the objective from the specimen. A beam splitter splits the light exiting the gradient-index lens into a first optical axis and a second optical axis. A first lens is aligned in the first optical axis between the beam splitter and a first camera to focus a magnified image at the first camera. A second camera is situated along the second optical axis from the rear principal plane of the objective so as to obtain unity magnification when the working distance of the objective is set at twice its focal length. Multiple magnifications can be obtained with a single objective by moving the optical system axially to set different working distances from a specimen, and by using multiple beam splitters, or combinations thereof.

    摘要: We disclose a method of electron-beam induced of etching the surface of a specimen in a charged-particle beam instrument, where the charged-particle beam instrument has first and second laser beams, an electron beam, and a gas-injection system for applying etchant gas to the surface. Etching is accomplished by applying a photolytic pulse from the first laser to the surface; applying a pyrolytic pulse from the second laser to the surface; and, applying an etchant gas to the surface at least during the pyrolytic pulse. Two or more alternating pyrolytic laser pulses and photolytic laser pulses may be applied to the surface. The stage supporting the specimen may be tilted relative to the axis of the electron beam before applying the electron beam to the surface of the specimen. The electron beam is applied to the surface of the specimen during the time the etchant gas is present at the surface.

    摘要: We disclose method for materials deposition on a surface inside an energetic-beam instrument, where the energetic beam instrument is provided with a laser beam, an electron beam, and a source of precursor gas. The electron beam is focused on the surface, and the laser beam is focused to a focal point that is at a distance above the surface of about 5 microns to one mm, preferably from 5 to 50 microns. The focal point of the laser beam will thus be within the stream of precursor gas injected at the sample surface, so that the laser beam will facilitate reactions in this gas cloud with less heating of the surface. A second laser may be used for cleaning the surface.

    摘要: A single-channel optical processing system for an energetic-beam instrument has separate sources for processing radiation and illumination radiation. The processing radiation and the illumination radiation are combined in a single optical path and directed to a sample surface inside the energetic-beam instrument through a self-focusing rod lens. The self-focusing rod lens thus has a working distance from the sample surface that will not interfere with typical arrangements of ion beams and electron beams in such instruments. A combination of polarizers and beam splitters allows separation of the combined incident radiation and the combined radiation reflected from the sample surface and returned through the same optical channel, so that the reflected radiation may be directed to an optical detector, such as a camera or spectrometer. In other embodiments, additional illumination of the sample surface is provided at an angle to the central axis of the self-focusing rod lens.

    摘要: A fiber probe device includes a fiber segment that has at least three sections. An uppermost section has the largest diameter; an intermediate section has an intermediate diameter, and a lowest section (tip) has the smallest diameter. The presence of the intermediate section enables control over the stiffness of the section located immediately above the tip as well as control over the mechanical resonance characteristic of the probe device when it scans a sample surface to be measured.
