摘要： Conductive paths in an integrated circuit are formed using multiple undifferentiated carbon nanotubes embedded in a conductive metal, which is preferably copper. Preferably, conductive paths include vias running between conductive layers. Preferably, composite vias are formed by forming a metal catalyst pad on a conductor at the via site, depositing and etching a dielectric layer to form a cavity, growing substantially parallel carbon nanotubes on the catalyst in the cavity, and filling the remaining voids in the cavity with copper. The next conductive layer is then formed over the via hole.

摘要： A memory gain cell for a memory circuit, a memory circuit formed from multiple memory gain cells, and methods of fabricating such memory gain cells and memory circuits. The memory gain cell includes a storage device capable of holding a stored electrical charge, a write device, and a read device. The read device includes a fin of semiconducting material, electrically-isolated first and second gate electrodes flanking the fin, and a source and drain formed in the fin adjacent to the first and the second gate electrodes. The first gate electrode is electrically coupled with the storage device. The first and second gate electrodes are operative for gating a region of the fin defined between the source and the drain to thereby regulate a current flowing from the source to the drain. When gated, the magnitude of the current is dependent upon the electrical charge stored by the storage device.

摘要： A gain cell for a memory circuit, a memory circuit formed from multiple gain cells, and methods of fabricating such gain cells and memory circuits. The memory gain cell includes a storage capacitor, a write device electrically coupled with the storage capacitor for charging and discharging the storage capacitor to define a stored electrical charge, and a read device. The read device includes one or more semiconducting carbon nanotubes each electrically coupled between a source and drain. A portion of each semiconducting carbon nanotube is gated by the read gate and the storage capacitor to thereby regulate a current flowing through each semiconducting carbon nanotube from the source to the drain. The current is proportional to the electrical charge stored by the storage capacitor. In certain embodiments, the memory gain cell may include multiple storage capacitors.

摘要： A field effect transistor is formed having wrap-around, vertically-aligned, dual gate electrodes. Starting with a silicon-on-insulator (SOI) structure having a buried silicon island, a vertical reference edge is defined, by creating a cavity within the SOI structure, and used during two etch-back steps that can be reliably performed. The first etch-back removes a portion of an oxide layer for a first distance over which a gate conductor material is then applied. The second etch-back removes a portion of the gate conductor material for a second distance. The difference between the first and second distances defines the gate length of the eventual device. After stripping away the oxide layers, a vertical gate electrode is revealed that surrounds the buried silicon island on all four side surfaces.

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.
