Systems and method for reducing the size of inertial measurement units are disclosed. In one embodiment, an inertial measurement unit assembly comprises: at least one inertial sensor configured to output uncompensated sensor data; an inertial isolator configured to isolate the at least one inertial sensor; an interface adapter, wherein the interface adapter includes at least one calibration alignment pin that is used as a reference point between the at least one inertial sensor, the inertial interface adapter and a vehicle to which the inertial interface adapter is attached. Furthermore, the inertial measurement unit is configured to output the uncompensated sensor data to a processing device located external to the inertial measurement unit.

A multi-axis integrated MEMS inertial sensor device. The device can include an integrated 3-axis gyroscope and 3-axis accelerometer on a single chip, creating a 6-axis inertial sensor device. The structure is spatially with efficient use of the design area of the chip by adding the accelerometer device to the center of the gyroscope device. The design architecture can be a rectangular or square shape in geometry, which makes use of the whole chip area and maximizes the sensor size in a defined area. The MEMS is centered in the package, which is beneficial to the sensor's temperature performance. Furthermore, the electrical bonding pads of the integrated multi-axis inertial sensor device can be configured in the four corners of the rectangular chip layout. This configuration guarantees design symmetry and efficient use of the chip area.

The present invention provides, in a physical quantity measuring system using a vibrator, a supporting structure of a vibrator for reducing the zero-point temperature drift of detection signal. It is provided a supporting member 22 for supporting a vibrator 1A with bonding wires 26. The supporting member 22 has a supporting plate 40 with an opening 25 formed therein to be positioned direct under a vibrator 1A, and a bonding wire 26 comprising a bonding end 29 to be bonded with the vibrator 1A, a fixed portion 26a fixed on the supporting plate 40 and a bent portion 28 direct under the opening 25. A distance "L1" between the bent portion 28 and a position 39 where the bonding wire 26 starts to protrude from the supporting plate 40 is 10 percent or more of a distance "L2" of the bent portion 28 and the bonding end 29.
摘要:
A method of fabricating a semiconductor comprises forming a plurality of stud bumps (110) in a pattern having a geometrical shape on a surface of a substrate (118), the pattern defining a periphery of a bonding area (114) on the surface of the substrate (118), and placing a solder material in the bonding area (114) such that the solder material is surrounded by the stud bumps (110). The solder material is heated to a temperature where the solder material begins to flow within the bonding area (114). A bonding surface of a die (130) is pressed onto the stud bumps (110) with a sufficient pressure to crush the stud bumps (110) a predetermined extent such that the solder material substantially evenly spreads between the stud bumps (110) within the bonding area (114). The solder material is then solidified to form a final solder area (132) that conforms to the geometrical shape of the pattern of stud bumps (110).
