At Fraunhofer ISIT the poly silicon surface micromachining process PSM-X2 for the production of vibrating micro electromechanical systems (MEMS) such as gyrometers or accelerometers is established. This process combines broad geometry flexibility of the MEMS structure together with a high operational pressure bandwidth. Competitive benefits are the use of a wafer-level packaging process with superior packing density and the integration of a high capacity getter film for low vauum levels and secured device lifetime. Since Inertial Measurement Units (IMU) require different sensor designs and concepts this process platform is uniquely suited for their common production.
