awards & honors
Leti PhD candidate Rana Alhalabi won the Best Poster Award at the 18th Non-Volatile Memory Technology Symposium in October 2018 in Sendai, Japan. This high-level international event brings together leading memory technology experts to discuss the state of the art in FLASH, FeRAM, PCRAM, RRAM, and MRAM. The award-winning poster presented the development of a high-density SOT-MRAM memory array using a single transistor by Alhalabi and her team*. They replaced one of the usual two transistors with a unidirectional diode.
The Design Automation Conference (DAC) has been bringing the IC chip design and design automation community together for five decades. Held in San Francisco, DAC 2018 featured sessions on design, of course, but also on embedded software and systems and automotive technology, security and privacy, IoT, design infrastructure, and smart systems. Leti engineer Olivier Debicki brought home the 2018 Designer Track Best Presentation Award for his talk on the EU H2020 project INSPEX, which applies multi-sensor obstacle detection technologies originally developed for automotive applications to navigation for the visually impaired. The CEA's SigmaFusionTM sensor fusion technology was used to develop a model of the environment from LiDAR, radar, and ultrasound sensors on a white cane, effectively creating a buffer zone to keep the user safe. Assisted living solutions for the disabled are not something you encounter every day at tech conferences. The entire project team can be proud not only of the award, but also of contributing to a project that will make a positive impact on the lives of the visually impaired.
The latest advances in materials science were spotlighted at the European Materials Research Society's E-MRS 2018 Spring Meeting in Strasbourg, France. E-MRS meetings stand out for their multidisciplinary philosophy and international positioning. The organization also actively supports innovation and achievement through awards, one of which went to Munique Kazar Mendes, who was completing her PhD at Leti at the time of the award. She came in second in the Solid State Ionics Symposium Best Poster competition for her research on the electrochemistry of resistivity changes in Te-based conductive-bridge memories.
The Americas International Meeting on Electrochemistry and Solid State Science (AiMES 2018), a joint conference of the 234th Meeting of the Electrochemical Society (ECS) and the XXXIII Congreso de la Sociedad Mexicana de Electroquimica (SMEQ)was held in Cancun, Mexico. AiMES meetings provide a valuable opportunity for researchers from government labs, academic institutions, and industry to share their latest results in a unique environment at the crossroads of electrochemical and solid state science.
Marouane Mastari won the Best Student Presentation Award at the SiGe, Ge, and Related Compounds: Materials, Processing, and Devices Symposium for his research on the coalescence of SiGe nano-pillars. Mastari took advantage of the wide range of state-of-the-art resources at Leti to characterize SiGe pillars grown on a SiO2 based nano-template at different stages of the coalescence process. This type of characterization at the very early stages of growth had not been done previously, and the insights gained could help improve semiconductor-industry processes.
The SPIE Advanced Lithography conference is the leading global lithography event,
showcasing a comprehensive lineup of lithography and patterning topics crucial to the
future of many technologies. Charles Valade brought home the Karel Urbanek Best Student Paper Award, sponsored by KLA Corporation, from the 2019 SPIE Advanced Lithography conference (Metrology, Inspection, and Process Control for Microlithography session) in San Jose, California. Valade, who is currently completing his PhD in 3D SEM computational metrology with Leti's Computational Lithography Group and STMicroelectronics' Resolution Enhancement Techniques team, developed a model to improve the 3D reconstruction of images captured using tilt-beam SEM. The results were coherent with conventional 3D measurement techniques and reliable reconstructions on patterns of various heights were completed using a single calibrated model. This award is proof that the kind of cooperation between scientific research and industrial R&D that Leti is known for is an effective strategy. As a young researcher at Leti, Valade is already making a name for himself in the international lithography community.
Leti research won one of two Best Paper Awards at the 19th International Workshop on Junction Technology 2019. IWJT is a high-level international event showcasing the latest advances in research on junction formation technology for semiconductor applications. Leti's Philippe Rodriguez and his team explored the impact of alloying elements Co and Pt on Ni-based contact technology with the goal of increasing the thermal stability of Ni-GeSn contacts. In particular, they studied the effects on the solid-state reaction and on surface roughness and electrical properties. Rodriguez attributes the win to the relentless determination, investment, and talent of PhD candidate Andrea Quintero, who joined Rodriguez's team in April 2017. Rodriguez was in good company at IWJT: the other Best Paper Award went to acclaimed international advanced materials scientist Sigefusa Chichibu of Tohoku University.
been a pioneer since the early days of electron spin qubits, will bring expertise in electron spin qubit manipulation in semiconductors. For Vinet, the ERC Synergy Grant will provide an opportunity to broaden her scientific scope and, especially, collaborate with basic research scientists.
topics like IoT, Industry 4.0, autonomous vehicles, and 5G communications. Florian Wolf, a PhD candidate at 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, 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 is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
