    摘要: A semiconductor microphone unit includes a semiconductor microphone chip having a diaphragm covering an inner hole of a support. The support is adhered onto the surface of a support substrate whose thermal expansion coefficient higher than the thermal expansion coefficient of the support via a thermosetting adhesive in such a way that the diaphragm is positioned opposite to the surface of the support substrate. The thermosetting adhesive has a tensile elastic modulus allowing a contraction of the support substrate to be transmitted to the support in a hardened state when the semiconductor microphone chip is cooled together with the support substrate. Thus, it is possible to reduce the tensile stress of the diaphragm, which occurs during the manufacturing of the semiconductor microphone chip, thus preventing the diaphragm from being unexpectedly reduced in strength; hence, it is possible to improve the sensitivity of the semiconductor microphone chip.

    摘要: A magnetic sensor comprises a thin-film-like magnetic tunnel effect element (magnetoresistive effect element) 11. A coil 21 is disposed in a plane under the magnetic tunnel effect element 11 and parallel to a thin-planar film surface of the element. The coil 21 is a double spiral type coil which includes a first spiral conductor portion 21-1 and a second spiral conductor portion 21-2. The magnetic tunnel effect element 11 is disposed between a spiral center P1 of the first conductor portion 21-1 and a spiral center P2 of the second conductor portion 21-2 in a plan view. The first and second conductor portions 21-1 and 21-2 are connected such that electric currents in the same direction pass through a part of the first conductor portion 21-1 that overlaps the magnetic tunnel effect element 11 in a plan view and through a part of the second conductor portion 21-2 that overlaps the magnetic tunnel effect element 11 in a plan view.

    摘要: A gate electrode material film is deposited on a substrate and formed with an opening for each pixel area, and thereafter a first insulating film and an emitter electrode material film are deposited. Slits for separation of emitter lines are formed by etching the emitter electrode material film at the area intersecting with gate lines to be later formed. Thereafter, a second insulating film is deposited and an element substrate is adhered to the second insulating film to remove the initial substrate. The gate electrode material film is thereafter patterned to form a plurality of gate lines and the emitter electrode material film is patterned to form a plurality of emitter lines.

    摘要: A vibration transducer (or a pressure transducer) is constituted of a cover, a plate, a diaphragm, and a substrate having a back cavity. The diaphragm is positioned above the substrate so as to cover the opening of the back cavity. The plate has a radial gear-like shape constituted of a center portion positioned just above the diaphragm and a plurality of joints. The cover horizontally surrounds the plate with slits therebetween so that the cover is electrically separated from the plate and is positioned above the periphery of the diaphragm. A plurality of pillar structures joins the plurality of joints of the plate so as to support the plate above the diaphragm with a gap layer therebetween. By reducing the widths of slits, it is possible to prevent foreign matter from entering into the air layer between the plate and the diaphragm.

    摘要: An easy and inexpensive process by which a concentrate of a given unsaturated fatty acid can be obtained from a mixture which has conventionally been difficult to concentrate. The process, which is for producing a concentrate of a desired isomer (a) from a conjugated fatty acid mixture (A), is characterized by comprising: a step in which the conjugated fatty acid mixture (A) is mixed with at least one unsaturated fatty acid (B) to obtain a mixture solution containing the isomer (a) dissolved therein; a crystallization step in which either crystals rich in the isomer (a) or crystals poor in the isomer (a) are precipitated from the mixture solution; and a solid-liquid separation step for obtaining the crystals rich in the isomer (a) or for obtaining a solution rich in the isomer (a) by removing the crystals poor in the isomer (a).

    摘要: A semiconductor device is produced using a housing having a hollow cavity for embracing a semiconductor sensor chip (e.g., a microphone chip) for detecting pressure variations and an LSI chip for driving the semiconductor sensor chip, both of which are mounted on a chip mount surface. An opening allowing the cavity to communicate with external space is formed at a prescribed position of the chip mount surface within the housing, wherein the LSI chip is positioned above the opening so as to cover at least a part of the opening of the housing. Thus, it is possible to reduce negative influences of environmental factors applied to the semiconductor sensor chip without using an environmental barrier, and it is possible to downsize the semiconductor device.

    摘要: Magnetoresistive devices are formed on the insulating surface of a substrate made of silicon. The devices are connected in series through an insulating film using a wiring layer formed on the surface of the substrate. An insulating film for passivation is formed to cover the devices and the wiring layer. A magnetic shield layer of Ni—Fe alloy is formed on the passivation insulating film through an organic film for relieving thermal stress to cover one of the devices. After removal of the sensor chip containing the magnetoresistive devices and other components from the wafer, the chip is bonded to a lead frame through an Ag paste layer by heat treatment. Preferably, the magnetic shield layer is made of a Ni—Fe alloy having a Ni content of 69% or less.
