Presentation of the waves research activities of the EDMINA team

The activities of the EDMiNA team are focused on the integration of innovative materials, the design, modeling, characterization, performance study and assessment of the reliability of electronic and photonic devices. Understanding and modeling the physical mechanisms are at the heart of our issues.

In this way, the group relies on recognized skills in metrology, optical and optoelectronic (from UV to IR), electromagnetic (from DC to 110 GHz) and acoustic characterization of materials through dedicated platforms, and multi-physical modelling, whether through the use of analytical calculation codes or numerical approaches (FEM, FDTD).

Reliability of optoelectronic components

The implementation of dedicated fine characterization methodologies and the modeling of the physical mechanisms of degradation of optical semiconductor components give the group excellent recognition with industrial partners in the field (3SP Technologies, Renault, CEA-LETI, III-V Lab, THALES, CNES, SUNNA Design, Amplitude Systems, ALPHANOV…). 

The projects are carried out within the framework of various programs, addressing the development and assessment of the reliability of different optoelectronic technologies (LEDs, laser diodes, photodetectors). Let us mention the “IDE2aL” project co-financed by the regional council (2014-2017) dedicated among other things to the fine characterization in temperature of power laser diodes and the highlighting of particular effects linked to the presence of defects (microplasma) likely to affect the life of these components under operational conditions. This work has led to an optimized design of 980nm GaAs diodes by the company 3SP Technologies.

Innovative Microelectronics Packaging

Included in this area are microdevices for electronics incorporating hybrid materials. The collaboration set up in 2015 with the NSERC/IBM Smarter Microelectronics Packaging for Performance Scaling Chair in close collaboration with ICMCB made it possible to finance a thesis in joint supervision with the University of Sherbrooke, which enabled the development of a ‘low-cost’ manufacturing process for capacitors based on thin films (∼ 200 nm) incorporating Ba0.6Sr0.4TiO3 nanoparticles synthesized by supercritical fluid.

 Capacitance densities close to the state of the art (1 to 2 uF.cm-2) have been obtained, demonstrating the promoting nature of this approach for the microelectronics industry. At the same time, on a European scale, the recognition of the group’s work in the field of the effects of packaging on the reliability of devices allows it to be involved in several European projects.

Integration of innovative materials

 The goal is to develop and characterize durable materials in order to integrate them into electronic and photonic devices with a high degree of miniaturization and at low cost.

Integrated optical microsensor

Background work, both fundamental and experimental, is carried out, making it possible to show the performance of a low-cost ring micro-resonator (OMR), and to identify the main design and production criteria carrying out a detection of water pollutants. With regard to the state of the art, the discriminating scientific element lies in the homogeneous detection (without surface functionalization) in the visible by measuring the changes in intensity (related to absorption) and wavelength resonance (linked to the change in optical index). In partnership with UMI LN2 (CRSNG funding), work is underway on the modeling and specific development of innovative resonant structures in integrated optics (OMR integrating porous sheath), targeting the detection of water pollutants.
