High-density memory research wins Best Poster Award at NVMTS2018 in Japan

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. 

This improved the area density by 20% and required less control logic, making the array suitable for high-density memory architectures. Alhalabi, who is investigating logic circuits and memory design with Spintec and Leti, came to the CEA to pursue her PhD after completing a Master's degree in Nanoelectronics and Nanotechnology at Grenoble-Alpes University. 

Leti engineer helps bring greater safety to the visually impaired

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.

ERC Consolidator Grant will drive advances in in-memory computing at Leti

European Research Council Consolidator Grants provide investigator-led funding to mid-career researchers with the goal of boosting the impact of their work and, ultimately, fueling innovation in Europe. Leti scientist François Andrieu, who leads the institute's advanced CMOS lab, was awarded a Consolidator Grant in 2018 for his My-CUBE project on 3D integration of a logic/memory cube for in-memory computing. 

His research will leverage non-volatile resistive memory, new energy-efficient nanowire transistors, and 3D monolithic technology to develop a functionality-enhanced system with advanced integration of logic and memory. The capacity to bring logic to memory/ storage will be a game changer for artificial intelligence, machine learning, data analytics, and any data-abundant computing system. More broadly, it will serve as a key computational kernel for the next generation of low-power, energy-efficient integrated circuits developed in Europe. Just 12% of the proposals received by the ERC were selected for funding in 2018, proof that Leti research is at the head of the class in Europe.

Nanocharacterization platform contributes to tomorrow's non-volatile memory

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 overriding purpose of her work is to pave the way for conductive bridge resistive memories (CBRAMs), currently in the running for the next generation of non-volatile memory. Kazar Mendes came to Grenoble from Brazil to complete her Master's in Electrochemistry at Grenoble Institute of Technology (2015) and her PhD at Leti (2018). Her thesis on subquantum resistive memories investigated the electrochemical reactions and ionic transport involved in resistive switching. According to Kazar Mendes, the Nanocharacterization Platform's ability to perform advanced analyses of complex structures like resistive memories helped position her research as a major contribution to the development and optimization of this technology.

Novel research on nanopillar growth wins student award at international conference

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.

Leti and STMicroelectronics support award-winning PhD research

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.
