Title: Superconducting magnetic shield container and its manufacture
Inventor: NUMATA KOICHI
IPC: H05K9/00
Filed: 1991-11-21
Abstract: PURPOSE:To realize a large magnetic shield container, by adopting structure wherein oxide superconducting layers and silver layers are alternately laminated. CONSTITUTION:A coating film composed of YSZ or (NiCrAlY alloy) as under coating material 2 is formed on the outer peripheral part of a base member 1 of an Ni based alloy cylinder or the like. A silver film 3 is sprayed to be 10-20mum thick. A bismuth based oxide film 4 is sprayed to be 40-60mum thick. The silver films 3 and the bismuth based oxide films 4 are laminated to form 5-10 layered structure, thereby forming a film of about 500-700mum in thickness in total. Alloy concentration of the siver film 3 is set 0.2 atomic% or larger. When the concentration is smaller than 0.2 atomic%, characteristics of alloy addition are not obtained. As alloy elements, Cu, Ca and Pb are used. Heat treatment temperature is different in the case of high temperature phase and in the case of low temperature case of bismuth based superconduction phase. In both cases, heat treatment is performed at a partial fusion temperature (880-890 deg.C). The film is turned into the state of half fusion, and then oriented. Thereby the superconducting layer in contact with the silver layer is easily oriented, and internal stress at the time of spraying is relieved by the silver layer.

Title: Multilayer printed wiring board
Inventor: ASAI MOTOO
IPC: H01L23/12
Filed: 1999-11-22
Abstract: PROBLEM TO BE SOLVED: To prevent the peeling of a conductor layer and an interlayer resin insulating layer and the crack of the interlayer resin insulating layer with a heat cycle condition and high temperature, high pressure and high humidity conditions by forming roughened layers on the whole surface of the lattice-like conductor layer. SOLUTION: Roughened layers 5 are formed on the whole surface of a conductor layer. The conductor layer is closely stuck to an interlayer resin insulating layer through the roughened layers 5. Thus, the conductor layer and the interlayer resin insulating layer are not peeled off even with a heat cycle condition and high temperature, high voltage and high humidity conditions. When the roughened layers 5 are formed on the side of the lattice-like conductor layer, a crack owing to a thermal expansion coefficient difference between the conductor layer and the interlayer resin insulating layer at the boundary of them can be suppressed. Since the lattice-like conductor layer operates as a power layer or a ground layer, a via hole 140 is connected but the roughened layers 5 are formed on the surface of the lattice-like conductor layer.  Thus, superior adhesion property with the via hole 140 is given. The lattice- like conductor layer is formed of an electroless plating film and an electrolytic plating film.
