In this paper we present a silicon based pressure sensor for high pressure applications. The sensor is based on fusion bonding and designed for a simple and a low-cost encapsulation scheme. The sensor can be designed for a maximum pressure in the range from 35 bar to 1500 bar and temperatures ranging from –40 °C to 120 °C and has a burst pressure exceeding 3000 bar. For proper performance of the sensor it is essential that the fusion bond inter-face is hermetic tight which will be one of the issues for discus-sion in this paper. Sensor design, fabrication and performance of the sensor will further be presented.
