    Abstract: Optimization techniques are disclosed for producing sharp and stable tips/nanotips relying on liquid Taylor cones created from electrically conductive materials with high melting points. A wire substrate of such a material with a preform end in the shape of a regular or concave cone, is first melted with a focused laser beam. Under the influence of a high positive potential, a Taylor cone in a liquid/molten state is formed at that end. The cone is then quenched upon cessation of the laser power, thus freezing the Taylor cone. The tip of the frozen Taylor cone is reheated by the laser to allow its precise localized melting and shaping. Tips thus obtained yield desirable end-forms suitable as electron field emission sources for a variety of applications. In-situ regeneration of the tip is readily accomplished. These tips can also be employed as regenerable bright ion sources using field ionization/desorption of introduced chemical species.

The first ion beam irradiation system has a liquid metal ion source that generates first ions for forming the first ion beam. The second ion beam irradiation system has a gas field ion source that generates second ions for forming the second ion beam. The first ion beam irradiated by the first ion beam irradiation system has a first beam diameter and the second ion beam irradiated by the second ion beam irradiation system has a second beam diameter smaller than the first beam diameter. The first and second ion beam irradiation systems are disposed relative to the sample stage so that axes of the first and second ion beams are orthogonal to a tilt axis of the sample stage.

    Abstract: A system for accessing circuitry on a flip chip circuit device with active circuitry and full-thickness bulk silicon includes a moveable surface for supporting and locating the circuit device in a plane, an infrared (IR) imaging device located at a defined perpendicular distance from a surface of the bulk silicon, the surface of the bulk silicon parallel to the plane and a milling chamber configured to direct an etchant and a focused ion beam to the surface of the bulk silicon, resulting in a gas-enhanced milling process that creates a milled cavity in the bulk silicon. The system produces an IR reflective material located at a base of the cavity, wherein the circuit device is located within a field of view of the IR imaging device such that the IR reflective material is brought into focus by moving the IR imaging device an adjustable distance perpendicular to the surface of the bulk silicon, and where the adjustable perpendicular distance is indicative of a depth of the cavity.

    Abstract: In an aperture for use in an ion beam optical system having its surface coated with a liquid metal, instability of an ion source attributable to sputtering and re-deposition of an aperture base material is prevented. A focused ion beam apparatus using a liquid metal ion source has an aperture for limiting an ion beam diameter. The aperture has a vessel formed with a recess having, at its surface lowermost point, an aperture hole through which the ion beam passes and a liquid metal mounted on the recess, the liquid metal being used for the liquid metal ion source. Preferably, the aperture may be minimized in area of aperture entrance hole inner surface which exposes the base material by tapering an aperture hole portion, by which the ion beam passes, on the downstream side.

    Abstract: An emitter of a Ga liquid metal ion source is constituted to include W12 of a base material and Ga9 of an ion source element covering a surface as construction materials. By making back-sputtered particles become elements (W and Ga) of the Ga liquid metal ion sour source, if back-sputtered particles attach to the Ga liquid metal ion source, contamination which may change physical characteristics of Ga9 does not occur. A W aperture is used as a beam limiting (GUN) aperture to place Ga of approx. 25 mg (of melting point of 30° C.) on a surface of a portion included in a beam emission region (Ga store). When emitting ions to the beam limiting (GUN) aperture, Ga in the emission region melts and diffuses on a surface of the beam emission region of the W aperture.
