Lecture content: This talk presents a novel composite sensor that is monolithically integrated with an accelerometer, a pressure sensor, and a thermometer by using a single-side-processed micromachining technique. Such composite sensors are highly demanded in tire pressure monitoring system (TPMS) applications. Based on heat convection, the accelerometer consists of a micro-heater and a pair of detector to measure the acceleration-induced temperature distribution change. Thermopile- and thermistor-based detectors both have been used to measure the temperature distribution change. In the on-chip integrated sensors, a low-stress silicon nitride thin film is used as the electric isolation layer, the pressure diaphragm, and the heating-insulating freestanding beams. The boron-doped polysilicon film is used as the piezoresistors, the heater, the thermopile, and the thermometer. After wafer level packaging with an aligned adhesive bonding technique, the 2.5 × 2.5 × 0.84 mm3 microsensor chips are promising for TPMS low-cost fabrication and volume applications.
