摘要： A method for isolating transistors and a microstructure for providing isolation for transistors includes a beam located on a substrate. The beam is formed from the same material as the substrate, preferably single crystal silicon, and is released so as to be suspended in the cavity and spaced apart from the substrate. The beam is supported in the cavity by a cantilever structure or by spaced pedestals, or both. One or more transistors are fabricated in the beam, and are thus isolated from the substrate and may be isolated from each other if desired. Contact beams may also be provided to contact the transistor electrodes for interconnection of adjacent transistors or connection of the transistors to electrical circuitry on the substrate. The contact beams also provide mechanical support for the beams.Multiple beams in side-by-side arrays or stacked arrays may be provided.

摘要： Through a silicon fabrication process, an emitter tip array is produced by electron beam or other suitable submicrometer scale lithography for precise location of the emitters. The emitter tips are formed by an oxidation process which ensures accurate and precise formation of tips having uniform radii. The process also utilizes the oxidation step to precisely align gate electrode apertures with respect to corresponding emitter tips so that large arrays can be formed with great accuracy and reliability.

摘要： Metal MEMS structures are fabricated from metal substrates, preferably titanium, utilizing micromachining processes with a new deep etching procedure to provide released microelectromechanical devices. The deep etch procedure includes metal anisotropic reactive ion etching utilizing repetitive alternating steps of etching and side wall protection. Variations in the timing of the etching and protecting steps produces walls of different roughness and taper. The metal wafers can be macomachined before forming the MEMS structures, and the resulting wafers can be stacked and bonded in packages.

摘要： A single-mask process for fabricating enclosed, micron-scale subsurface cavities in a single crystal silicon substrate includes the steps of patterning the substrate to form vias, etching the cavities through the vias, and sealing the vias. Single cavities of any configuration may be produced, but a preferred embodiment includes closely spaced cavity pairs. The cavities may be separated by a thin membrane, or may be merged to form an enlarged merged cavity having an overhanging bar to which electrical leads may be connected. A three-mask process for fabricating enclosed cavities with electrical contacts and electrical connections is also disclosed.

摘要： A high aspect ratio field emission or tunnelling probe is fabricated utilizing a single crystal reactive etching and metallization process. The resulting field emission probes have self-aligned single crystal silicon sharp tips, high aspect ratio supporting posts for the tips, and integrated, self-aligned gate electrodes surrounding an electrically isolated from the tips. The gate electrodes are spaced from the tips by between 200 and 800 nm and metal silicide or metal can be applied on the tips to achieve emitter turn on at low operational gate voltages. The resulting tips have a high aspect ratio for use in probing various surface phenomena, and for this purpose, the probes can be mounted on or integrated in a three-dimensional translator for mechanical scanning across the surface and for focusing by adjusting the height of the emitter above the surface.
