摘要： PROBLEM TO BE SOLVED: To solve a problem that when a metal post on a wafer is connected, as a terminal, with a circuit board in a semiconductor package, e.g. a wafer level CSP(ChipSize/Scale Package) using no wiring board (interposer), a conductive layer covering the post is possibly stripped by a stress acting on the post and development of a technology for surely preventing it is needed. SOLUTION: A resin protrusion 4 on the insulation layer 3 of a wafer 1 is coated with a conductive layer 160, and a post 7 arranged to disperse and absorb a stress through deformation of the resin protrusion 4 is employed. Furthermore, the conductive layer 160 covering the resin protrusion 4 covers a part of the side face 4c of the resin protrusion 4 and at least a part of the top part 4a so that the post 7 deforms easily in the semiconductor package 20.

摘要： PROBLEM TO BE SOLVED: To provide an oxide superconductive cable that is strong against stress by enhancing mechanical strength, can prevent superconductive characteristics from being deteriorated, and can reduce a.c. loss by reducing eddy current loss in carrying alternating current. SOLUTION: This oxide superconductive cable is composed by winding, around a pipe-like former 17, multiple composite superconductive conductors made by additively sticking a metal tape on a tape-like superconductive conductor 18. The superconductive conductor 18 is formed by installing multiple oxide superconductive cores inside a metal sheath. It is preferable that a dislocated superconductive tape unit 15 is formed by intertwining and dislocating the composite superconductive conductors and the metal tape is formed from a metallic material having an electric resistance and strength higher than those of the metal sheath.

摘要： PROBLEM TO BE SOLVED: To provide a superconductive cable capable of reducing a.c. loss in carrying alternating current and preventing channeling. SOLUTION: This superconductive cable 10 is composed of, a dislocated superconductive tape unit 15 formed by intertwining and dislocating multiple tape-like superconductive conductors 18 by winding around a tube body 17. On each of the superconductive conductors 18, increased-resistance film is formed by performing a sulfurization process on the surface of a tape-like superconductive strand which is formed by flattening a superconductive strand, which equips a core part made of a superconductor or a core part having a material that can be made into a superconductor by heat treatment inside a base made of a sheath material. The increased-resistance film has an electric resistivity higher than that of the sheath material forming the base.

摘要： PROBLEM TO BE SOLVED: To increase the capacity of an oxide superconducting cable by equalizing a current passing through respective superconductors and an effect of a self-magnetic field and increasing critical current density. SOLUTION: This oxide superconducting cable 10 is formed by disposing a plurality of superconductors 20 formed by covering an oxide superconducting core 21 with a sheath 22, around a pipe-shaped formed 40. Superconducting strand 30 consisting of a plurality of superconductors 20 is wound around the former 40, thereby forming a superconducting strand layer 11. The respective superconductors 20 are stranded so as to be positioned on the front layer side and back layer side of the superconducting strand layer 11 alternately in order to equalize the effect of self-magnetic field.

摘要： PROBLEM TO BE SOLVED: To prevent the normal conductive transition of a superconductive coil due to generated heat on the normal conductive transition of a persistent current switch, by providing a superconductive connection conductor with a high critical current at the superconductive wire contact of the superconductive coil and the persistent current switch. SOLUTION: An opening/closing switch 8 is closed when taking out a storage energy externally, and a persistent current switch 7 is shifted to a normal conductive state. At this time, the resistance of the switch 7 increases, thus generating Joule loss heat. The heat is transferred to a permanent current switch conductor 3, thus increasing the temperature of the conductor 3. However, a superconductive connection conductor 1 with a higher critical temperature than the conductors is installed at the connection between the superconductive coil conductor 2 and the conductor 3 while it is in direct contact with both conductors. And, the temperature of the conductors 2 and 3 increases at the connection and current flows through the conductor 1 as far as the conductor 1 does not cause normal conductive transition even if the normal conductive state results. Therefore, current flowing to the side of the switch 7 decreases, thus suppressing amount of heat being generated.

摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method for a polycrystal thin film by which the divergent angle of an ion beam generated from an ion source is controlled and the crystal orientation control effect is improved. SOLUTION: The manufacturing method for the polycrystal thin film is executed by forming the polycrystal thin film on a base material 22 by depositing constituting particles, which are a target provided within an evacuatable film formation processing vessel while the base material is irradiated with the ion beam generated from the ion source 39 at an angle of incidence of 50 to 60 deg. to a normal H on the film formation surface of the base material 22 when the constituting particles are beated out by sputtering and are deposited on the base material 22. In such a case, the divergent angle Δθ of the ion beam calculated by the equation: Δθ (d/2L) is controlled by changing a beam bore (d) of the ion source 39 and the transporting distance (the distance between the beam port 49 and the base material 22) L of the ion beam.
