摘要： Carbon nanotube field effect transistors, arrays of carbon nanotube field effect transistors, device structures, and arrays of device structures. A stacked device structure includes a gate electrode layer and catalyst pads each coupled electrically with a source/drain contact. The gate electrode layer is divided into multiple gate electrodes and at least one semiconducting carbon nanotube is synthesized by a chemical vapor deposition process on each of the catalyst pads. The gate electrode has a sidewall covered by a gate dielectric and at least one semiconducting carbon nanotube adjacent to the sidewall of the gate electrode. Source/drain contacts are electrically coupled with opposite ends of the semiconducting carbon nanotube to complete the device structure. Multiple device structures may be configured either as a memory circuit or as a logic circuit.

摘要： A conductive layer in an integrated circuit is formed as a sandwich having multiple sublayers, including at least one sublayer of oriented carbon nanotubes. The conductive layer sandwich preferably contains two sublayers of carbon nanotubes, in which the carbon nanotube orientation in one sublayer is substantially perpendicular to that of the other layer. The conductive layer sandwich preferably contains one or more additional sublayers of a conductive material, such as a metal. In one embodiment, oriented carbon nanotubes are created by forming a series of elongated parallel catalyst strips on a horizontal surface, and growing carbon nanotubes from the catalyst in the presence of a directional flow of reactant gases.

摘要： A dielectric in an integrated circuit is formed by creating oriented cylindrical voids in a conventional dielectric material. Preferably, voids are formed by first forming multiple relatively long, thin carbon nanotubes perpendicular to a surface of an integrated circuit wafer, by depositing a conventional dielectric on the surface to fill the area between the carbon nanotubes, and by then removing the carbon nanotubes to produce voids in place of the carbon nanotubes. A layer of dielectric and voids thus formed can be patterned or otherwise processed using any of various conventional processes. The use of a conventional dielectric material having numerous air voids substantially reduces the dielectric constant, leaving a dielectric structure which is both structurally strong and can be constructed compatibly with conventional processes and materials.

In another embodiment, oriented carbon nanotubes are grown on the surface of a conductive material in the presence of a directional flow of reactant gases and a catalyst.

摘要： Methods for selecting semiconducting carbon nanotubes from a random collection of conducting and semiconducting carbon nanotubes synthesized on multiple synthesis sites carried by a substrate and structures formed thereby. After an initial growth stage, synthesis sites bearing conducting carbon nanotubes are altered to discontinue synthesis at these specific synthesis sites and, thereby, halt lengthening of the conducting carbon nanotubes. Synthesis sites bearing semiconducting carbon nanotubes are unaffected by the alteration so that semiconducting carbon nanotubes may be lengthened to a greater length than the conducting carbon nanotubes.

摘要： Vertical device structures incorporating at least one nanotube and methods for fabricating such device structures by chemical vapor deposition. Each nanotube is grown by chemical vapor deposition catalyzed by a catalyst pad and encased in a coating of a dielectric material. Vertical field effect transistors may be fashioned by forming a gate electrode about the encased nanotubes such that the encased nanotubes extend vertically through the thickness of the gate electrode. Capacitors may be fashioned in which the encased nanotubes and the corresponding catalyst pad bearing the encased nanotubes forms one capacitor plate.

摘要： A conductive layer in an integrated circuit is formed as a sandwich having multiple sublayers, including at least two sublayers of oriented carbon nanotubes. A first sublayer is created by growing carbon nanotubes in a first direction parallel to the chip substrate from a catalyst in the presence of a reactant gas flow in the first direction, and a second sublayer is created by growing carbon nanotubes in a second direction parallel to the substrate and different from the first direction from a catalyst in the presence of a reactant gas flow in the second direction. The first and second directions are preferably substantially perpendicular. The conductive layer sandwich preferably contains one or more additional sublayers of a conductive material, such as a metal.
