Specifically, the task involves a collaboration between ST Microelectronics, the Laboratoire Hubert Curien and the company Orsay Physics (Tescan). This last is specialized in the conception of scanning electron microscopy (SEM) devices, coupled with a particular technology called focused ion beam (FIB). This is a technique of choice for failure detection, which uses a high-energy ion beam to perform matter ablation on a chip (sample slicing for inspection), while simultaneous imaging of the sample at a nanoscale is performed thanks to a SEM column (<span class="Object" role="link" id="OBJ_PREFIX_DWT3673_com_zimbra_url"><span class="Object" role="link" id="OBJ_PREFIX_DWT3680_com_zimbra_url"><a href="https://en.wikipedia.org/wiki/Focused_ion_beam" target="_blank" rel="noopener" data-mce-href="https://en.wikipedia.org/wiki/Focused_ion_beam"><span style="color: windowtext; text-decoration: none;" data-mce-style="color: windowtext; text-decoration: none;">https://en.wikipedia.org/wiki/Focused_ion_beam</span></a></span></span>).
