摘要:
Upon fixing fine particulate active element members AE1 to AE3, which are carbon nanotube, rod-shaped semiconductor crystal, or the like, in an electronic device at predetermined positions thereof respectively, a method for producing an electronic device includes: dispersing the fine particulate active element members in a dielectric liquid 12 and filling the liquid in a space between a process-objective substrate 20 and a mask 1 which is placed opposite to the substrate and which has predetermined pattern electrodes P1C, P1L, P1R formed therein; and applying a predetermined voltage to the predetermined electrodes to concentrate the fine particulate active element members at positions which correspond to positions of the pattern electrodes, respectively. In this state, a light is irradiated to the substrate and the fine particulate active element members in the liquid so as to fix the fine particulate active element members to the substrate by a photochemical reaction. Thus, a high-performance electronic device using carbon nanotubes or rod-shaped semiconductor crystal can be manufactured at low cost.

Disclosed is a method for producing regularly arranged nanowires from a nanowire-forming material on a substrate. Said method is characterized by the following steps: a) the material is introduced into a carrier liquid at a load remaining at least three orders of magnitude below the loading capacity of the carrier liquid; b) a guiding member is placed on the substrate; c) the substrate is heated to a temperature at which a thin film of the carrier liquid undergoes spinodal decrosslinking on the substrate; d) a film of the carrier liquid that is loaded with material is applied to the heated substrate in the surroundings of the guiding member, where a gradient of the average film thickness is obtained perpendicular to the contour of the guiding member; and e) the carrier liquid is evaporated such that the material is left along lines extending perpendicular to the gradient of the film thickness.

摘要:
A method for forming carbon nanotube field effect transistors, arrays of carbon nanotube field effect transistors, and device structures and arrays of device structures formed by the methods. The methods include forming a stacked structure including 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 completed device structure includes a gate electrode with 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.
