Magelan inertial MEMS foundry

Standard inertial MEMS foundry technology

Tronics Microsystems proposes Magelan, its core inertial sensor technology, as an open MEMS foundry platform with design kit for customer specific design. This thick SOI technology with Vacuum/Hermetic WLP enables the production of industrial, automotive and aerospace-grade capacitive MEMS inertial sensor dies (accelerometers, vibration sensors, gyros).

Standard process for 1 to 3-axis accelerometers, gyros and vibration sensors


Our open inertial MEMS foundry platform enables the production of your most innovative designs with the following benefits:

  • From single-axis to multi-axis capacitive MEMS designs
  • High sensitivity and high signal-to-noise
  • High reliability thanks to C-SOI and Hermetic WLP with getter
  • Small die size and low cost
  • Ease of integration with standard wire-bonding
