    摘要: Solutions permit or facilitate faster and/or easier processing involving loading or unloading of a work module into a process station. For example, the work module may be a processing tube or the like and the process station may be a heating station such as a tube furnace or the like. In one embodiment, the loading is from a single side of a process station. In one embodiment, the work module includes inlets and outlets for fluid flow, with both inlets and outlets being closer toward one side of the work module than the other side.

    摘要: In one embodiment, an apparatus for fabricating nanostructure-based devices on workpieces includes: a stage for supporting a workpiece, a radiating-energy source, and a feedstock delivery system. The workpiece has catalyst thereon. The radiating-energy source is configured to focus radiating energy toward a work region of the workpiece to directly heat catalyst at the work region, without directly heating catalyst at one or more other work regions of the workpiece. The feedstock delivery system delivers feedstock gas to the catalyst at the work region. The feedstock delivery system includes a feedstock heating system. The feedstock heating system is configured to heat the feedstock gas not merely by any global heating of the chamber or any direct excitation of gas over the work region by the focused radiating energy. Preferably, the radiating-energy source emits multiple prongs of radiating energy.

    摘要: A field emission device having bundles of aligned parallel carbon nanotubes on a substrate. The carbon nanotubes are oriented perpendicular to the substrate. The carbon nanotube bundles may be up to 300 microns tall, for example. The bundles of carbon nanotubes extend only from regions of the substrate patterned with a catalyst material. Preferably, the catalyst material is iron oxide. The substrate is preferably porous silicon, as this produces the highest quality, most well-aligned nanotubes. Smooth, nonporous silicon or quartz can also be used as the substrate. The method of the invention starts with forming a porous layer on a silicon substrate by electrochemical etching. Then, a thin layer of iron is deposited on the porous layer in patterned regions. The iron is then oxidized into iron oxide, and then the substrate is exposed to ethylene gas at elevated temperature. The iron oxide catalyzes the formation of bundles of aligned parallel carbon nanotubes which grow perpendicular to the substrate surface. The height of the nanotube bundles above the substrate is determined by the duration of the catalysis step. The nanotube bundles only grow from the patterned regions.

    摘要: In one embodiment, an apparatus for fabricating nanostructure-based devices on a workpiece includes: a stage for supporting a workpiece, a radiating-energy source, and a feedstock delivery system. The workpiece has catalyst deposited thereon. The workpiece includes multiple work regions (e.g., dies). The feedstock delivery system is for delivery of feedstock gas to said catalyst. The feedstock delivery system is configured to directly heat catalyst on at least one die via simultaneously emitted multiple prongs of radiating energy. Preferably, the feedstock delivery system includes a feedstock heating system that is configured to heat the feedstock gas not merely by any global heating of a chamber containing the work region or any direct excitation of gas over the work region by the radiating energy.
