    摘要: According to this method for manufacturing a multilayer glass-ceramic circuit board, a green sheet laminate is fired in a non-oxidizing atmosphere in a first firing step so that a void content of at least 10% is maintained and strength of the ceramic laminate is increased. Then the laminate is fired in an oxidizing atmosphere in a second firing step so that the organic binder contained in the laminate is removed and the residual carbon content is at most 200 ppm. Thereafter the laminate is fired in a reducing atmosphere in a third firing step to reduce the oxidized conductor circuit. Finally, the laminate is fired in a non-oxidizing atmosphere in a fourth firing step to densify the ceramic laminate. The firing temperature in the first, second and third steps is 100.degree.-200.degree. C. lower than the softening point of the glass and the firing temperature in the fourth step is higher than the softening point of the glass and lower than the melting point of the conductor.

    摘要: A ceramic thin film hybrid circuit board is provided by flattening the surface of a ceramic multi-layer interconnection substrate, forming capture pads on the flattened surface, filling spaces between the capture pads with an insulating layer composed of a glass material or an organic resin material, grinding the resultant surface until the capture pads are exposed to flatness, and laminating a plurality of thin film interconnection layers on the flattened surface. The ceramic thin film hybrid circuit board has an increased package density of mounted electronic parts such as LSIs and the like because failures of thin film interconnection layer generated owing to the roughness of the surface of the ceramic substrate, defects such as voids and the hollows produced with the capture pads are greatly reduced, and is very suitable for large scale electronic computers, in which the wiring length is reduced so as to reduce the signal delay.

    摘要: A method for forming conductor layers of substrates for mounting LSIs and the like and a fabrication method of multilayer substrates are disclosed. These methods comprise steps of forming a metal underlayer having a shape similar to that of a conductor pattern on the substrate, forming an insulation layer over portions of the substrate which are not covered by the metal underlayer, and disposing a plating layer on the metal underlayer by carrying out electroless plating while using the insulation layer as the resist and thereby forming conductors. As compared with a conventional conductor layer forming method, the number of fabrication steps is reduced. And the elimination of the surface grinding step facilitates the fabrication.

    摘要: A gas detection device and a method for detecting a gas where gas information including concentrations of gas components in a mixed gas, concentration, presence of specific gas components and the like is detected by measuring, e.g., the output voltages of a plurality of gas sensors having different gas selectivities. The gas selectivities, as a characteristic constant of the specific gas sensor, was previously determined. The measured output voltages and gas selectivities are then used for solving plural simultaneous equations for gas concentrations.
