This extension allows new innovative technological modules to be inserted in, or made compatible with, industrial flows up to completely pioneered technology routes that enable edge AI, HPC, in memory computing, photonics, power electronics and other high-end applications.
CEA-Leti’s 300mm wafer-line extension is intended to accelerate innovation projects with fab partners using 300mm wafers.
Targeted technological routes and related targeted applications for the 300mm line extension include:
- memory: phase-change RAM (PCRAM), oxide-based resistive memory (OxRAM), conductive-bridging RAM (CBRAM)
- vertical image sensors
- photonics: III-V on silicon, integrated photonics…
- power electronics: insulated-gate bipolar transistors (IGBT)
- HPC and edge AI: FD-SOI and derivatives, such as sequential stacking and Si qbits for quantum computing
- 3D wafer-to-wafer or die-to-wafer bonding, hybrid bonding: substrates and layer transfer for advanced substrates in collaboration with Soitec.
CEA-Leti's advanced CMOS strategy targets FD-SOI research through the development of modules to the economic and technological limits of scaling, and complements the extension of the 300mm platform for edge-AI applications, analogue applications, RF and power electronics.
This strategy is based on a mix of priorities of CEA-Leti’s partners and its researchers’ ideas and includes cloud and edge computation, high-volume communication, multi-modality interaction and energy conservation.
“Our 300mm line will help Leti continue this strategy by accessing dimensions that make it possible to address the pressing challenges associated with emerging technologies, such as quantum, nanowires and sequential 3D integration,” explained Emmanuel Sabonnadière, CEA-Leti CEO. “CEA-Leti’s industrial partners are now able to develop or test their disruptive technologies and their designs on state-of-the-art equipment, while benefiting from the institute’s R&D expertise, to achieve improved component performance, direct comparison with the ecosystem and easier technology transfers from lab to fab.”
The implementation of this 300mm line is being funded by the Auvergne Rhone Alpes region and by the French government.
