LETi

LETi

The Laboratoire d’électronique des technologies de l’information (LETi) is a French research laboratory specializing in microelectronics, nanotechnology, and integrated systems. Founded to advance semiconductor research and transfer innovations to industry, LETi operates at the interface between public research and private industry, collaborating with universities, research agencies, and multinational corporations. It has played a role in national and European initiatives in micro- and nanoelectronics, contributing to applied research, prototyping, and technology transfer.

History

LETi traces its institutional roots to postwar French efforts to develop semiconductor expertise alongside institutions such as Commissariat à l'énergie atomique et aux énergies alternatives and Centre national de la recherche scientifique. During the late 20th century semiconductor expansion, LETi engaged with programs linked to Plan Calcul and national industrial policy that sought to cultivate domestic capabilities in microelectronics. In the 1990s and 2000s, LETi participated in European research frameworks like the Framework Programme (EU), aligning with initiatives such as ENIAC and ECSEL Joint Undertaking to foster cross-border collaboration. The laboratory deepened ties with regional innovation ecosystems in Grenoble and the Auvergne-Rhône-Alpes area, interacting with institutions such as the Grenoble Institute of Technology and the Institute polytechnique de Grenoble.

Research and Development

LETi’s R&D focuses on areas spanning CMOS scaling, advanced lithography, heterogeneous integration, and sensors. Its teams have contributed to nanofabrication methods compatible with production processes pioneered by firms like STMicroelectronics and GlobalFoundries. Research themes include design of low-power circuits in the tradition of works at CEA-LETI partner laboratories, exploration of quantum devices akin to programs at CEA and CEA Grenoble, and integration of photonics with electronics comparable to efforts by IMEC and Fraunhofer Society. LETi researchers publish and present findings at venues such as the International Electron Devices Meeting, the IEEE International Solid-State Circuits Conference, and the SPIE Photonics West conference, while participating in consortia funded by entities like the European Commission and national agencies such as the Agence nationale de la recherche.

Technology and Products

LETi has developed process flows, prototype chips, and demonstrators spanning MEMS, image sensors, and power electronics. The laboratory’s work on advanced CMOS nodes and back-end-of-line integration targets applications similar to those pursued by Qualcomm, Intel, and Samsung Electronics. LETi prototypes have included silicon-based detectors used in projects associated with Thales Group and sensor systems for aerospace partners like Airbus. In power electronics, LETi’s contributions align with silicon carbide and gallium nitride device advances linked to companies such as Infineon Technologies and Rohm Semiconductor. Photonic integrated circuit work complements industry roadmaps championed by Nokia and Cisco Systems, while microelectromechanical systems developments relate to product lines from Bosch Sensortec and STMicroelectronics.

Industry Partnerships and Collaborations

LETi operates through formal partnerships with corporations, startups, and academic institutions. Collaboration models mirror those seen in alliances like SEMATECH and IMEC cooperative frameworks, enabling technology transfer, joint development, and pre-competitive research. The laboratory engages with multinational firms such as NXP Semiconductors, Analog Devices, and Texas Instruments on process integration and device characterization. LETi has participated in startup incubation ecosystems comparable to CentraleSupélec spin-off initiatives and collaborates with public innovation clusters including Minalogic and SATT (Sociétés d'Accélération du Transfert de Technologies). Cross-border projects have included partners from Germany, United Kingdom, Italy, and Spain under EU instruments like Horizon 2020.

Organization and Locations

LETi is structured to combine multidisciplinary research groups—device physics, microfabrication, system integration, and characterization—working alongside technology transfer teams and industrial liaison offices. The laboratory is co-located with research and fabrication infrastructure in the Grenoble area, a cluster that includes institutions such as Université Grenoble Alpes and facilities comparable to the Minatec innovation campus. Additional synergies connect LETi to national centers such as CEA Grenoble and regional engineering schools like INP Grenoble. Its organizational model features joint projects with corporations and incubators, mirroring governance patterns seen at research centers like CEA List and Fraunhofer-EAS.

Impact and Recognition

LETi’s contributions have influenced national and European semiconductor roadmaps and helped bridge laboratory research to commercial products. Its demonstrators and pilot lines have accelerated deployment timelines for technologies adopted by partners like STMicroelectronics and Thales Group, and its collaborative outputs have fed into standards and industrial benchmarks recognized by bodies such as SEMI and IEC. LETi personnel and projects have received awards and acknowledgments from scientific forums including the IEEE and national honors from French institutions like Ministère de l’Enseignement supérieur, de la Recherche et de l'Innovation. The laboratory’s role in regional innovation has reinforced Grenoble’s reputation alongside other clusters such as Sophia Antipolis and Silicon Saxony.
