摘要

This paper presents an oil-filled isolated high temperature piezoresistive pressure sensor with the pressure range of 0 - 60 MPa. The piezoresistive sensor chip with the size of 3 mm×3 mm×0.525 mm is fabricated using MEMS (Micro Electro-Mechanical System) and SOI (Silicon on Insulator) technologies. It is packaged on the glass with thickness of 0.5 mm by anodic bonding in vacuum environment. By high temperature oil-filled process, the sensor is fabricated with the sensor chip, corrugated diaphragm and mechanical base. The experimental results show that the accuracies of the sensor are better than 0.2%FS (Full Scale) and the temperature drifts are less than 0.02%FS°C-1 at 20 °C - 175 °C. Therefore, it can be used to measure the pressure reliably under high temperature in the fields of aerospace, petroleum and chemical industry, mobile and military industry etc.
