摘要： A magnetometer with only a SET operation for initiating a magnetic orientation within a magnetic field sensor based on anisotropic magnetoresistive (AMR) technology. Within the magnetometer, the relative orientations of the respective X, Y and Z axes detectors are maintained by a package in which all detectors are mounted on a single assembly with the Z axis sensor displaced and held orthogonal to the other two sensors by potting material. Shorting bars on respective barber pole structures are provided with a geometry that allows for closer placement of adjacent barber poles to one another. The barber pole structures are deposited in a nested orientation which provides for balanced resistance legs in a Wheatstone bridge construction.

摘要： A foldable substrate is provided that includes a first substrate portion with a first upper surface and a second substrate portion with a second upper surface. A foldable bridge portion couples the first substrate portion to the second substrate portion. The foldable bridge portion includes a coupling strip that extends from the first substrate portion to the second substrate portion with a gap corresponding to a portion of the coupling strip where the gap is defined between the first and second substrate portions by removing portions of a starting wafer substrate. The first and second portions, in one embodiment, include magnetic field sensors and the foldable bridge portion can be bent to arrange the two portions at a predetermined angle to one another. Once bent, the sensor package can be incorporated into a magnetic field sensor assembly to be integrated with other control circuitry.

摘要： Micro-machined capacitive sensors implemented in micro-electro-mechanical system (MEMS) processes that have higher sensitivity, while providing an increased linear capacitive sensing range. Capacitive sensing is achieved via variable-area sensing, which employs a transduction mechanism in which the relationship between changes in the capacitance of variable, parallel-plate capacitors and displacements of a proof mass is generally linear. Each respective variable, parallel-plate capacitor is formed by a finger/electrode pair, in which both the finger and the electrode have rectangular tooth profiles that include a plurality of rectangular teeth. Because changes in the overlapping area of the finger and the electrode are multiplied by the number of rectangular teeth, while the standing capacity of the micro-machined capacitive sensor remains relatively high, the sensitivity of the micro-machined capacitive sensor employing variable-area sensing is significantly increased per unit area of the finger and the electrode.
摘要翻译：在微机电系统（MEMS）工艺中实现的微加工电容传感器具有更高的灵敏度，同时提供增加的线性电容感测范围。通过可变区域感测实现电容感测，其采用转换机制，其中可变平行板电容器的电容变化与校准质量的位移之间的关系通常是线性的。每个可变平行板电容器由手指/电极对形成，其中手指和电极均具有包括多个矩形齿的矩形齿廓。由于手指和电极的重叠区域的变化乘以矩形齿的数量，而微加工的电容式传感器的静态容量保持相对较高，所以采用可变面积感测的微加工电容传感器的灵敏度手指和电极的每单位面积显着增加。

摘要： A system and method for testing and calibrating integrated sensor devices that improves the manufacturing test throughput of the devices. The system includes a tester, a temperature controller, and at least one probe station including a thermal chuck. The chuck can be heated to specified temperatures to achieve variable heating of a wafer, PCB, or pallet disposed thereon. The temperature controller adjusts the temperature of the chuck to a first specified level. The tester performs at least one first measurement of the output offset of each integrated sensor embodied as a die on the wafer, or as a device on the PCB or pallet. Next, the temperature controller adjusts the temperature of the chuck to a second specified level, and the tester performs at least one second measurement of the output offset of each integrated sensor at the second temperature level. The offset temperature coefficient (OTC) of each sensor is calculated based upon the output offset measurements performed at the first and second temperature levels, and optimal settings for calibrating the respective sensors are determined based upon the calculated OTC values. After the temperature of the chuck is brought back down to the first specified level, the tester programs the output offset calibration settings into each sensor.
