A superconducting material made of tungsten or molybdenum containing a specified amount of silicon, a wiring made of this superconducting material, and a semiconductor device using this wiring.The above-mentioned superconducting material undegoes no damage even in the steps of heat treatments effected after the formation of a wiring therefrom by virtue of its high melting point, and can be very easily patterned by reactive ion etching using SF.sub.6 as an etching gas, which has heretofore been generally employed. These features, in which conventional superconducting materials are lacking, allow the superconducting material of the present invention to exhibit excellent properties particularly when used in the wirings of a semiconductor device.

There is provided an information processing device in which an application of an electronic device provides a service to a user, the information processing device including a processor; and a memory that includes instructions, which when executed, cause the processor to execute the following steps: associating the application with a processing flow; associating the processing flow with a scope of authorization of an external service; retrieving the scope of the authorization of the external service required by the processing flow associated with the application; retrieving authorized information representing a scope of authorization of the external service authorized by the user; and providing, for each external service, information indicating whether the external service is authorized, based on a result of comparing the scope of the authorization of the external service required by the processing flow with the scope of the authorization of the external service authorized by the user.
摘要:
A first CVD dielectric layer is deposited on a surface of a semiconductor substrate. Next, low-k layers are deposited in at least two different steps to form one of a via-layer dielectric film and a wiring-layer dielectric film on the first CVD dielectric layer. Immediately after the depositions, thermal treatment is performed. A second CVD dielectric layer is deposited on the low-k layers. A groove is formed in the second CVD dielectric layer and the low-k layers. A metal layer is deposited on that structure, filling the groove. The metal layer is removed from the second CVD dielectric layer by chemical mechanical polishing.

The invention provides a method for manufacturing a semiconductor device with reduced dishing and erosion. In this method for manufacturing a semiconductor device, the convex/concave pattern is planarized by relatively moving a substrate having the convex/concave pattern on the surface and a polishing tool with pressing the convex/concave surface of the substrate on the polishing tool. The polishing tool is provided with a grindstone 10 having a plurality of polygonal segments 20, which comprises abrasive 23 that is bonded together with resin 24 and contains pores 22. The polygonal segments are arranged so that corners of three or more polygonal segments are not located near each other.

A superfine electronic device is disclosed, which is constructed by atomic fine lines having a structure in which a plurality of atoms are arranged on one or a plurality of straight lines, in a ring shape or on curves with a size of atomic level, and which includes elements for doping electrons and holes. Using these atomic fine lines, it is possible to integrate semiconductor elements utilizing pn junctions at an atomic level with a high density. A groove having a sufficiently small size is formed in an insulating film disposed on a substrate. Then, atoms or molecules are supplied on the substrate and in the groove, which and are heated to a temperature sufficiently high for moving the atoms or molecules during or after the supply thereof to form a quantum fine line at edge portions of the groove.

In an atomic switch, opposite ends of an atom wire are connected to an input and output, and a switching gate is connected to a switching power supply. An input signal is outputted when a switching atom is connected to the atom wire, whereas an input signal is not outputted when the switching atom is moved to disconnect from the atom wire. There are provided an atom wire having a plurality of atoms arranged in a line or in a plurality of lines, in a ring shape, or in a curved line, and a switching gate made of an atom wire. The atom wire is switched by the field effect of the switching gate.
