Abstract:
A method for forming a uniform and dense carbon nanotube-dispersed film irrespective of the characteristics of the carbon nanotube-dispersed liquid and the type of substrate, and a method for manufacturing a semiconductor device having excellent electrical characteristics with less variation in characteristics are provided. The method for forming the carbon nanotube-dispersed film includes steps of coating a substrate (110) with a carbon nanotube-dispersed liquid containing carbon nanotubes (1101) dispersed in a solvent, cooling droplets (102) of the carbon nanotube-dispersed liquid to increase the viscosity of the solvent, evaporating the solvent to uniformly precipitate the carbon nanotubes (1101) and form a carbon nanotube coating film (1012), forming, on the carbon nanotube coating film (1012), a coating film of a carbon nanotube-dispersed liquid (1013) with higher carbon nanotube concentration, and evaporating the solvent from the coating film of carbon nanotube-dispersed liquid (1013) to form a film having dispersed carbon nanotubes (1022).
Abstract:
According to one embodiment, a broadband transition to joint a via structure and a planar transmission line in a multilayer substrate is formed as an intermediate connection between the signal via pad and the planar transmission line disposed at the same conductor layer. The transverse dimensions of the transition are equal to the via pad diameter at the one end and strip width at another end; The length of the transition can be equal to the characteristic dimensions of the clearance hole in the direction of the planar transmission line or defined as providing the minimal excess inductive reactance in time-domain according to numerical diagrams obtained by three-dimensional full-wave simulations.
Abstract:
PURPOSE:To obtain a transporting device for transporting crushed ice continuously to a fish tank by providing a crushed ice discharger having vanes rotatable in a horizontal plane to a storage tank. CONSTITUTION:A tank 30 for storing crushed ice temporarily is made cylindrical. Consequently, bridging phenomenon of crushed ice occurs scarcely on the bottom wall 46 of the storage tank. A discharger 45 is arranged at the bottom wall 46 side of the storage tank 30 in order to scrape crushed ice stored on the bottom wall 46 and feed positively to discharge ports 50, 51. Consequently, bridging phenomenon of crushed ice does not occur on the bottom wall 46 of the storage tank. Crushed ice fed to the discharge ports 50, 51 is further fed to crushed ice pressure feed pipes 64, 64 by means of rotary valves 52, 53 then carried to a specific fish tank by means of compressed air. Since bridging phenomenon does not occur on the bottom wall 46 of the storage tank, negative pressure is produced in the storage tank 30 when crushed ice is carried in thus moving the crushed ice smoothly from the storage tank 30 to the rotary valves 52, 53.

Abstract:
A memory cell comprising a MOSFET formed on a principle surface of a semiconductor substrate and an information storage capacitor having a storage electrode formed in or on the substrate so as to contact with a drain region of the MOSFET, and a capacitor electrode formed adjacent to the storage electrode with a capacitor insulator film being sandwiched between the storage electrode and the capacitor electrode. The storage electrode is connected to the drain region of the MOSFET through a thin barrier layer which is formed between the drain region and the storage electrode region so as to prevent impurities in the storage electrode from being diffused into the drain region.
Abstract:
An input terminal and an input protective resistor of an N-type diffusion layer connected thereto are provided on a P-type semiconductor substrate. First and second N-type MOS transistors for internal circuit are connected to a grounding wiring at respective source diffusion layers. The first MOS transistor is located at closer distance from the input protective resister than the second MOS transistor. The source diffusion layer of the first MOS transistor and the grounding wiring are connected via a high melting point metal layer wiring, such as a tungsten silicide or so forth to increase a resistance to improve electrostatic breakdown potential. Accordingly, the distance between the input protective resistor and the first MOS transistor can be made smaller to eliminate dead space around the input protective resistor to enable reduction of a chip area.
