Investigate the electrical /mechanical reliability of cutting-edge PMUT (Piezoelectric Micromachined Ultrasound Transducer) devices for large-area electronics applications

Traditional microphone units focus on human perceptible sound waves (between 20 Hz and 20 kHz). Acoustic development also focuses on ultrasound, compromising the frequencies above the detection limit of the human ear (from 20 kHz to several GHz). These sound waves can be used for a wide variety of applications, including medical imaging, therapeutic treatment, non-destructive testing and position localization of objects.

In the past years, imec has led the development of novel technologies that promise to meet all requirements of future micro-sound systems. This internship will focus on the electrical /mechanical characterization and reliability assessment of cutting-edge PMUT (Piezoelectric Micromachined Ultrasound Transducer) devices for large-area electronics applications, to outline the impact of materials and integration schemes on the actuation performance and to identify the root causes of reliability failures for proposing further improvement of the stacks. You will be trained in the use of advanced electrical / mechanical characterization tools and you will carry out reliability assessment by using state-of-the-art characterization techniques, benchmarking different PMUT technologies. Careful and critical data analysis will be an essential part of the task, as well as proposing alternative characterization strategies for effective reliability assessment. You will work in a dynamic R&D environment and you will be expected to regularly present and discuss your results with a team of experts in the field. Therefore, a proficient use of English is also required. A good command of data analysis software (Matlab, Origin, Python, etc.) will be considered a strong plus.
