CEA-Leti @ECTC 2024

From 5/28/2024 to 5/31/2024
Denver, Colorado, USA

​​​​​​​​​CEA-Leti to Report Latest Results on 3-Layer Integration,High Density TSVs & Other Packaging Topics at ECTC 2024, May 28-31​​

GRENOBLE, France – April 23, 2024 – CEA-Leti will present seven papers and one poster on its latest developments in microelectronics packaging, including three covering 3-layer integration, at the Electronic Components and Technology Conference (ECTC), May 28-31, in Denver.

A pioneer in FD-SOI technology, the institute is at the forefront of heterogeneous 3D integration and enables the combination of More Moore and More than Moore technologies. 3D integration and advanced packaging technologies are becoming mainstream for modular, high-bandwidth, low power consumption and efficient system architectures from consumer and automotive applications to high performance computing (HPC) and edge AI multi-layer smart imagers developed in the frame of IRT Nanoelec.

 From high-density interconnection (fine pitch hybrid bonding DtoW and WtoW) to ultra-thin stacking layer interconnection with high density TSV and low temperature process, CEA-Leti is pushing the limits of 3D integration. It also is preparing the next generation of quantum computing with a complete set of packaging technologies.    ​
