Abstract: Methods of producing microrods for electron emitters and associated microrods and electron emitters. In one example, a method of producing a microrod for an electron emitter comprises providing a bulk crystal ingot, removing a first plate from the bulk crystal ingot, reducing a thickness of the first plate to produce a second plate, and milling the second plate to produce one or more microrods. In another example, a microrod for an electron emitter comprises a microrod tip region that comprises a nanoneedle that in turn comprises a nanorod and a nanoprotrusion tip. The microrod and the nanoneedle are integrally formed from a bulk crystal ingot by sequentially: (i) removing the microrod from the bulk crystal ingot; (ii) coarse processing the microrod tip region to produce the nanorod; and (iii) fine processing the nanorod to produce the nanoprotrusion tip.

Abstract: Method for preparing site-specific, plan-view lamellae from multilayered microelectronic devices. A focused ion beam that is directed, with an etch-assisting gas, toward an uppermost layer of a device removes at least that uppermost layer and thereby exposes an underlying layer over, or comprising, a target area from which the site-specific, plan-view lamella is to be prepared, wherein the focused ion beam is in a face-on orientation in removing the uppermost layer to expose the underlying layer.

Abstract: Implanting a material in a pattern hardens the material in the pattern for subsequent etching. When the region is etched, by ion beam sputtering, chemically enhanced charged particle beam etching, or chemical etching, a thicker structure remains because of the reduced etch rate of the hardened pattern. The invention is particularly useful for the preparation of thin lamella for viewing on a transmission electron microscope.

Abstract: Sample pillars for x-ray tomography or other tomography scanning are created using an innovative milling strategy on a Plasma-FIB. The strategies are provided in methods, systems, and program products executable to perform the strategies herein.
