awards & honors
A team of scientists from CEA-Leti and the University of Rennes, France won an award for their paper* on electronically-steerable transmitarray antennas at the 13th European Conference on Antennas and Propagation (EuCAP) held in Krakow, Poland in the spring of 2019. CEA-Leti's Antonio Clemente was the principal author of the paper and presenter at the associated poster session. According to Clemente, "The awards are given for technical excellence, of course. But criteria like originality and innovation, significance to the AP community, potential impact, and clarity of presentation are also considered. Receiving one of these awards is a mark of the excellence of the proposed work at the international state of the art. Presenting our work at EuCAP also raised our profile worldwide, leading to a new partnership between CEA-Leti and a major Asian electronics manufacturer and early-stage talks with another manufacturer. Our paper and poster presentation reviewed CEA-Leti's research with IETR (University of Rennes) on electronically-steerable transmitarrays. Specifically, two transmitarrays with 20×20 and 14×14 elements were prototyped and characterized for operation in switchable circular or linear polarization. Wide electronically-steerable beam scanning was successfully demonstrated.
Emilio Calvanese Strinati and Antonio Clemente won a 2019 ETRI Journal Best Paper Award for their contribution to the EU-South Korea 5GCHAMPION project (coordinated by CEA-Leti) to develop the first fully-integrated and operational 5G testbed, which was showcased at the PyeongChang 2018 Olympic Winter Games. According to Emilio, "The award is an honor and a testament to our long-standing collaboration with ETRI and other Korean partners." Antonio said, "As a researcher at CEA-Leti, this award represents a major milestone, marking a decade of innovation and research on 5G." ETRI Journal grants the award to the best original paper published in the journal each year, selected by an editorial board made up of internationally-recognized researchers.
The 2018 15th Workshop on Positioning, Navigation and Communications (WPNC) brought together stakeholders spanning industry and academia to discuss hot tech topics like IoT, Industry 4.0, autonomous vehicles, and 5G communications. Florian Wolf, a PhD candidate at CEA-Leti, received the WPNC Best Paper Award for research that could lead to an alternative to Global Navigation Satellite System positioning for a wide range of IoT applications. The joint award recognized research Wolf conducted with Jean-Baptiste Doré, Xavier Popon, Sébastien de Rivaz, François Dehmas (Leti), and Jean-Pierre Cances (the University of Limoges) on a new location technique that utilizes phase-coherent multi-channel processing of narrowband signals. According to Wolf, CEA-Leti's capacity to innovate at all stages, from theoretical research through to proof-of-concept implementations, was instrumental in this award-winning work.
CEA-Leti and its partners in the EU PYCSEL project (coordinated by CEA-Liten) won an OE-A award (for multifunctional demonstrators utilizing organic and printed electronics) for their contributions to the development of a large conformable fingerprint sensor, ultimately for government and automotive (biometric driver identification) applications. CEA-Leti scientist Jean-François Mainguet, who drew on his prior fingerprint acquisition expertise, said, "This award recognizes some of my patented innovations in the fingerprint acquisition domain related to the use of pyroelectric material—PVDF-TrFE in this case—as a thermal sensing material. This was only one aspect of the project, however, and CEA-Liten and the other European project partners also contributed their diverse know-how, in what turned out to be an exemplary collaborative R&D project."
CEA-Leti scientists Olivier Savry, Thomas Hiscock, and Mustapha El Majihi won the 2019 European Cybersecurity Week "Best Technical Book" award for their book entitled Sécurité matérielle des systèmes : Vulnérabilité des processeurs et techniques d'exploitation* [Systems hardware security: Vulnerability of processors and operating techniques].
The book, written for IT and electronics developers and students, provides a thorough review of hardware vulnerabilities in the processors that power our electronic systems. The authors also describe vulnerabilities specific to memory, programs, and peripheral devices, and give an update on the latest known threats.
European Cybersecurity week is a leading international cybersecurity event. The book was selected by a panel of industrial cybersecurity experts (from Nokia, Airbus, and other companies) coordinated by PEC (Pôle d'Excellence Cyber), a French cybersecurity cluster.
A paper on "Active Interposer Technology for Chiplet-Based Advanced 3D System Architectures*" authored by CEA-Leti scientists won the Best Session Paper award at the IEEE 69th Electronic Components and Technology Conference (ECTC) held in Las Vegas in May 2019. Their groundbreaking work details the first successful integration of chiplets on a fully packaged and tested active silicon interposer with state-of-the-art, 20 µm-pitch, 3D interconnects—an advance that will ultimately support high-performance computing (HPC) applications.
Perceval Coudrain, a former STMicroelectronics engineer who came to CEA-Leti in 2018 to conduct research on 3D integration, FanOut wafer-level packaging, and embedded microfluidics, is particularly pleased about this award. He said, "Our paper was a group endeavor. It is also a wonderful example of the kind of long-term, multidisciplinary research we do at CEA-Leti. We were able to leverage the active interposer chiplet our designers have been promoting for years in a realistic 3D integration and packaging concept, overcoming some major technological hurdles in the process."
CEA-Leti PhD student Rana Berro won the Professor Raj Mittra special prize at the 2020 IEEE International Workshop on Antenna Technology (iWAT 2020) in Bucharest, Romania. The award came for her poster "Analysis of the Effects of Conductivity on Small Antenna Characteristics" authored with Serge Bories and Christophe Delaveaud. In this original research, which was inspired by work dating back to the middle of the last century, analytical formulations of electromagnetism were used to develop a circuit model, which was then used to test the fundamental limits of electrically small antennas. Today, electromagnetic simulators tend to be used for this kind of research.
Berro's team was able to predict the essential characteristics of miniature antennas without resorting to the simulators. Berro, who is from Lebanon, said, "The award was a boost to my self-confidence after some serious issues my family in Lebanon was facing that made it difficult for me to focus on my work during the notoriously difficult second year of the PhD, when many researchers tend to feel stuck. The award restored my faith in my abilities and made me proud to be part of one of the world's leading research organizations."
CEA-Leti CMP specialists Daniel Scevola and Yorrick Exbrayat brought home a Best Session Paper Award from ECTC in Las Vegas in May 2019 for their 3D chiplet integration work. In a world-first, their team successfully integrated chiplets on a fully processed, packaged, and tested active silicon interposer.
According to Daniel, "The award is recognition of the strong synergies between our teams at CEA-Leti and the complementarity of our scientists' profiles." This type of 3D integration will play an important role in tomorrow's high-performance computing (HPC) systems.
