    摘要: A capacitive semiconductor acceleration sensor capable of efficiently performing a self-diagnostic procedure without having to provide any separate electrodes for self-diagnosis purposes. The acceleration sensor includes a beam portion that is deformable upon application of acceleration thereto in a direction at right angles to the elongate direction thereof to thereby exhibit a spring function. The sensor also includes a movable electrode and fixed electrodes which are integrally formed with the beam portion. The sensor is operable to detect the acceleration while applying between the movable electrode and fixed electrodes a periodically changeable signal to derive an output voltage variable in potential with a differential capacitance change of capacitors between the both electrodes. Here, a detection signal for detection of such acceleration and a self-diagnosis signal are selectively applied while permitting creation of quasi-acceleration at the movable electrode due to application of the self-diagnosis signal, wherein a ratio of a frequency of the self-diagnosis signal to a resonance frequency of the beam portion in its deformation direction is set so that the resultant resonance magnification of such beam portion is more than or equal to one time upon application of the self-diagnosis signal.

    摘要: Herein disclosed is a semiconductor pressure sensor and a method of manufacture. The sensor includes a plate having a recess in its main surface. A diaphragm has a lower surface therof bonded to a first main surface of the plate and formed so as to have an upper surface having no holes therein. A piezoresistive layer is formed so as to be in contact with the diaphragm and is positioned so as to be at least partially over the recess. The resistance of the piezoresistive layer provides an indication of pressure applied to the diaphragm. The manufacturing method includes forming a piezoresistive layer of a single crystal substrate in a diaphragm without any recrystallization.

    摘要: In a manufacturing method for a semiconductor device having a coil layer part on a substrate, two support substrates each having a flat surface are prepared, and a component member is formed on the flat surface of each of the support substrates. The component member includes a wiring portion having a predetermined pattern and an insulation film surrounding the wiring portion. The wiring portion is provided with a connecting portion exposing from the insulation film. A coil layer part is formed by opposing and bonding the component members formed on the support substrates to each other while applying pressure in a condition where the flat surfaces of the support substrates are parallel to each other. A coil is formed in the coil layer part by connecting the wiring portions through the connecting portions.

    摘要: An optical device includes: a silicon substrate; a plurality of silicon oxide columns having a rectangular plan shape; and a cavity disposed between the columns. Each column has a lower portion disposed on the substrate. Each column has a width defined as W1. The cavity has a width defined as W2. A ratio of W1/W2 becomes smaller as it goes to the lower portion of the column. A core layer provided by the columns and the cavity can have the thickness equal to or larger than a few dozen μm easily. Therefore, connection loss between a light source and the device is reduced.

    摘要: A semiconductor device has a semiconductor wafer having sensing portions exposed on a surface thereof and an adhesive sheet attached to the semiconductor wafer as a protective cap to cover the sensing portions. The adhesive sheet is composed of a flat adhesive sheet and adhesive disposed generally on an entire surface of the adhesive sheet. Adhesion of the adhesive is selectively reduced by UV irradiation to have adhesion reduced regions, and the adhesion reduced regions face the sensing portions. The protective cap can be produced with high productivity, and securely protect the sensing portions when the semiconductor wafer is diced and is transported.
