Integrated circuit device and method of producing the same

An integrated circuit device having vias having good resistance to migration causing the breaking of a wiring line, or an integrated circuit device having a wiring structure that is fined by breaking the limit of lithography technique is provided. The former device comprises a plurality of elements fabricated on a semiconductor substrate, wiring lines for making the elements and the integrated circuit device function, and vias for interconnecting wiring lines in separate layers, the via being formed of one or more cylindrical structures made up of carbon atoms. The latter device comprises a plurality of elements fabricated on a semiconductor substrate and wiring members for making the elements and the integrated circuit device function, at least part of the wiring members being formed of one or more cylindrical structures made up of carbon atoms. The latter device is preferably manufactured by a method comprising using a CVD process for the formation of the cylindrical structures, while applying a direct current electric field so as to grow the cylindrical structures in one direction, or applying an alternating current electric field so as to grow the cylindrical structures in two directions. A semiconductor device using a carbon nanotube and a method of forming a pattern using a carbon nanotube as a mask are also disclosed.

Method for preparing allyl surface-active macromonomer

The invention discloses a method for preparing an allyl surface-active macromonomer, which is characterized by comprising the following steps: adding 20 portions of alkylphenol polyoxyethylene ether (CmH2m+1-C6H4-O-(CH2CH2O)nH, n is equal to 1 to 60, and m is equal to 1 to 20), 10 to 900 portions of solvent and 0.1 to 15 portions of catalyst into a three-mouth reaction flask with a reflux condensation device, and reacting the mixture for 1 hour under stirring at the room temperature; increasing temperature to 30 to 95 DEG C, adding 0.5 to 20 portions of allyl chloride into the reaction product, and continuously reacting for 6 to 48 hours; distilling the reaction product under reduced pressure to remove the solvent so as to obtain a crude product; and performing silica gel column chromatographic separation to obtain allyl alkylphenol polyoxyethylene ether with the yield of 70 to 95 percent. The allyl alkylphenol polyoxyethylene ether has excellent surface activity, and can be directly used as a surfactant. A water-soluble copolymer synthesized by taking the allyl alkylphenol polyoxyethylene ether as a surface-active macromonomer has the function of tackifying, or reducing solution surface tension and water-oil interfacial tension, and can be taken as a tackifying copolymer or a macromolecular surfactant for improving the oil recovery ratio.

Method for preparing 4-vinyl benzyl surface-active macromonomer

The invention discloses a method for preparing a 4-vinyl benzyl surface-active macromonomer, which is characterized by comprising the following steps: adding 20 portions of alkylphenol polyoxyethylene ether (CmH2m+1-C6H4-O-(CH2CH2O)nH, n is equal to 1 to 60, and m is equal to 1 to 20), 10 to 900 portions of solvent and 0.1 to 15 portions of catalyst into a three-mouth reaction flask with a reflux condensation device, and reacting for 1 hour under stirring at the room temperature; increasing temperature to 30 to 90 DEG C, adding 0.5 to 25 portions of 4-vinyl benzyl chloride into the reaction product, and continuously reacting for 6 to 48 hours; distilling the reaction product under reduced pressure to remove the solvent so as to obtain a crude product; and performing silica gel column chromatographic separation to obtain 4-vinyl benzyl alkylphenol polyoxyethylene ether with the yield of 62 to 94 percent. The 4-vinyl benzyl alkylphenol polyoxyethylene ether has excellent surface activity, and can be directly used as a surfactant. A water-soluble copolymer synthesized by taking the 4-vinyl benzyl alkylphenol polyoxyethylene ether as a surface-active macromonomer has the function of tackifying, or reducing solution surface tension and water-oil interfacial tension, and can be taken as a tackifying copolymer or a macromolecular surfactant for improving the oil recovery ratio.

Fiber-optic endoscope used for half-grouting sleeve and machining method of fiber-optic endoscope and application of fiber-optic endoscope

The invention discloses a fiber-optic endoscope used for a half-grouting sleeve and machining method of the fiber-optic endoscope and application of the fiber-optic endoscope, and relates to the technical field of sleeve detecting and monitoring. A grouting cavity is formed in the half-grouting sleeve. The bottom end of a steel bar is fixedly connected with a concrete structure layer. The upper part of the steel bar is fixedly connected into the grouting cavity. An outer pipe is made of transparent materials and fixedly connected with the cutting surface of the steel bar. The top end of the outer pipe is plugged through a stopper. The bottom end of the outer pipe extends from the bottom of the half-grouting sleeve to the exterior of the half-grouting sleeve. The side wall of the outer pipeis provided with a tick-mark line. The fiber-optic endoscope is arranged in the outer pipe and can slide in the outer pipe. The observation end, a probe and optical fiber of the fiber-optic endoscopeare used for being connected with a display screen, obtaining images and transmitting image information correspondingly. The fiber-optic endoscope can intuitively, clearly and quantitatively obtain the grouting fullness of the interior of the half-grouting sleeve, judge accurately the construction quality of the half-grouting sleeve, and deal with unqualified parts in time so as to avoid the influence of the half-grouting sleeve with unqualified construction quality on the overall safety of the housings.
