•  Support the product development of various MEMS-based ultrasound transducers, including design/simulation and process development

•  Handle MEMS design software such as L-edit, KLayout, Clewin or similar

•  Improve designs of transducers using analytical and FEM models

•  Read and analyze scientific articles and patents

•  Identifying patentable ideas and design improvements.

•  Conduct basic microfabrication activities, including:

-  Spin coating of photoresist, baking, and development

-  UV exposure in mask-aligners or maskless lithography systems

-  PVD tools (e.g., e-beam evaporation, sputtering systems)

-  Usage of inspection tools like profilometers and interferometers

•  Perform electromechanical and acoustic characterization activities, including:

-  Electrical tests (using impedance analyzers, vector network analyzers, etc)

-  Vibration characterization (using laser Doppler vibrometer)

•  Data analysis and signal processing using MATLAB or Octave
