PRESENTATION
CONTEXT
The nanotechnology market suffers deeply from the lack of industrial trust in technologies that are highly innovative but not fully demonstrated. The complete applicative potential of nanotechnologies can only be reached if the academic and industrial stakeholders are able to propose operational procedures to assess the reliability of nanomaterial-based electronic devices (or nanodevices).
Due to the particularities of nanoscale physics, nanodevices are more sensitive than traditional objects to a large realm of loadings (chemical, mechanical, thermal, ...). Moreover, degradation mechanisms affect nanodevices at different scales, from the nanoscale of the constitutive components to the macroscale of substrates and electric contacts. As a consequence damage phenomena involved in the ageing process are both highly multiphysical and multiscale.
OBJECTIVES
The aim of the PLATINE project is to provide suitable procedures to tackle the nanoreliability question, by coupling the standard nano-electronics methods (imaging, characterization, modeling) to the mechanics-based reliability framework.
The core of PLATINE is an experimental platform enabling the application of multiphysics loadings, i.e. electrical, mechanical, thermal, environmental, on nanodevices, while their electro- thermo-mechanical response is monitored at various scales. This platform is essential to pinpoint where and why failure occurs in the devices, as well as to assess systematically device lifetime. Jointly, the platform will provide capabilities for ex-situ analyses of the micro and nanoscale mechanisms responsible for failure initiation. Additionally, the PLATINE plateform is crucial to provide relevant data for the development and the assessment of fatigue models and lifetime predictions tailored to the physics of nanodevices.
The project brings together interdisciplinary and complementary expertise from different research teams: one team from the field of mechanical reliability (LMS), one team specialized in nanoelectronics (LPICM) and one team specialized in civilian applications of nanosensors (LISIS at IFSTTAR Université Paris-Est).
