A connection assembly includes a sensor substrate, a layer substrate coupled to the sensor substrate so as to face an upper surface of the sensor substrate, and a wire connected between the sensor substrate and the layer substrate. The sensor substrate includes first and second projections provide on the upper surface of the sensor substrate and extending in an extension direction along the upper surface of the sensor substrate. The wire has a first end sandwiched between the layer substrate and the first projection, and a second end sandwiched between the layer substrate and the second projection. The connection assembly provides reliable connection.

A wiring-buried glass substrate includes a glass substrate and a first wiring. The glass substrate includes a first surface, a second surface perpendicular to the first surface, and a third surface facing the first surface. The first wiring includes a first pillar portion and a first beam portion. The first pillar portion extends in a first direction perpendicular to the first surface of the glass substrate. The first beam portion is connected to a first surface of the first pillar portion and extends to a second direction perpendicular to a second surface of the glass substrate. The first wiring is buried in the glass substrate. The first surface of the first beam portion is exposed from a third surface of the glass substrate.

An acceleration sensor includes a weight portion having a recess section and a solid section, beam portions, a movable electrode provided on the opposite surface of the weight portion from an open surface of the recess section to extend over the recess section and the solid section, a first fixed electrode arranged at the opposite side of the movable electrode from the recess section, and a second fixed electrode arranged at the opposite side of the movable electrode from the solid section. The acceleration sensor detects acceleration using a change in capacitance between the movable electrode and the fixed electrodes caused by rotation of the weight portion. The beam portions are shifted toward the recess section such that an angle between a perpendicular line extending from a gravity center position of the weight portion to the rotation axis and a surface of the movable electrode becomes equal to 45 degrees.

Acceleration sensor

An acceleration sensor includes a CV conversion circuit, an AD conversion circuit, and first and second registers. The CV conversion circuit outputs a voltage corresponding to the capacitance changes between a movable electrode and each of first and second fixed electrodes disposed to face the movable electrode. The AD conversion circuit is connected to the CV conversion circuit and has a first detection range and a second detection range. The first register is connected to the AD conversion circuit and holds a first value. The second register is connected to the AD conversion circuit and holds a second value. The first value contains information about an acceleration in the first detection range, and the second value contains information about an acceleration in the second detection range. The first and second values indicate accelerations in the same direction.

An electrostatic capacitance sensorincludes a semiconductor substrate. A first fixing plateis joined to a one-side surfaceof the semiconductor substrate, and a second fixing plateis joined to other-side surfaceof the semiconductor substrate, whereby a space portion S is formed. Then, static electricity suppressing meansfor suppressing static electricity from being generated in the space portion S is provided in the electrostatic capacitance sensor

Electrostatic capacitance sensor

An acceleration sensor includes: a rectangular moving electrode; a pair of beams which connect to centers of two opposite sides of the moving electrode, and support the moving electrode freely swingably; and first and second fixed electrodes which are provided on one side and other side of a boundary line, respectively, and are arranged to be opposed to a front surface of the moving electrode at a predetermined interval. A straight line that connects the pair of beams to each other is taken as the boundary line. Then, on a back surface of the moving electrode, first and second recessed portions are formed on one side of the boundary line and the other side thereof, respectively.

A semiconductor acceleration sensor comprises: a frame having an opening inside thereof; flexible beams extending from the frame to the inside of the opening of the frame; a weight suspended from and supported by the beams so that the weight can freely move; piezoresistors to be mounted on the beams and to vary the resistance values in response to accelerations which work on the piezoresistors. The frame comprises damper plate portions, each of which covers a part of the opening spanning from a corner portion of two neighboring sides of the frame on the side of the opening to the inside of the opening, and each of which serves serve as a stopper to limit movement of the weight. The weight has corner portions which face the corner portions, respectively, and each of which is chamfered to have a shape of arc or a polygonal line consisting of at least three sides as seen in plan view. Thereby, the breaking strength of each stopper is increased, and hence a semiconductor acceleration sensor having superior shock resistance can be obtained.

A flexible area is joined at one end via a thermal insulation area to a semiconductor substrate which becomes a frame and at an opposite end to a moving element . The thermal insulation area is made of a thermal insulation material a resin such as polyimide or a fluoridated resin. The flexible area is made up of a thin portion S and a thin film M different in thermal expansion coefficient. When a diffused resistor formed on the surface of the thin portion S is heated, the flexible area is displaced because of the thermal expansion difference between the thin portion S and the thin film M, and the moving element is displayed with respect to the semiconductor substrate
