    摘要： A semiconductor pressure sensing apparatus includes a metallic stem having a diaphragm and a semiconductor sensor bonded to the diaphragm. The semiconductor sensor includes a gauge section and first and second bonding pads. The gauge section is configured to be deformed according to a deformation of the diaphragm. The first and second bonding pads are respectively connected to different positions of the gauge section so that an electrical resistance between the first and second bonding pads can change with a change in the deformation of the diaphragm. The gauge section is formed to a semiconductor layer of an silicon-on-insulator substrate. The semiconductor sensor is directly bonded to the diaphragm by activating contact surfaces between the semiconductor sensor and the diaphragm.

    摘要： A capacitance of a capacitor member, which varies according to a dynamic force such as an acceleration force imposed on the capacitor member, is detected by a detecting circuit. The detecting circuit is composed of an operational amplifier and a switched capacitor circuit connected in parallel to each other. A reset time (t), during which a feedback capacitor in the switched capacitor circuit is discharged, is set to satisfy the following formula: t>(ΔC+m)/n, where ΔC is an initial capacitance of the capacitor member, and n and m are constant factors having values in certain ranges. By setting the reset time (t) according to the above formula, an amount of acceleration imposed on the capacitor member is accurately detected even when the capacitor member has a certain level of the initial capacitance.

    摘要： A semiconductor device includes a first semiconductor substrate, a second semiconductor substrate, and a sealing member. The first semiconductor substrate has a surface and includes a sensing portion on the surface side. The sensing portion has a movable portion. The first semiconductor substrate and the second semiconductor substrate are bonded together to form a stacked substrate. The stacked substrate defines a hermetically sealed space for accommodating the sensing portion between the first and second semiconductor substrates. The stacked substrate further defines a recess extending between the first semiconductor substrate and the second semiconductor substrate to penetrate an interface between the first semiconductor substrate and the second semiconductor substrate. The sealing member is located in the recess.
