Leti’s 200 mm and 300 mm research wafers, which until recently have been ground up and disposed of after use, are now sent to an aluminum foundry for recycling. The foundry was audited and its procedures for managing confidentiality were validated, and the recycling program went live in September. The nature of the advanced components […] >>

A team of researchers from Spintec, Institut Néel, and CNRS obtained the high-speed motion of skyrmions in a three-layered platinum/cobalt/magnesium oxide material, setting a record of 100 meters per second. Even more impressive: the record was achieved at low current densities and at ambient temperature! The key? Layers just a few nanometers thick, synonymous with […] >>

Tomorrow’s autonomous vehicles could use infrared (IR) imagers to scan the road and surrounding environment. The EU Heliaus project, coordinated by LYNRED*, is investigating the potential of this technology. The project’s eleven partners, which include Leti, will receive EU funding of more than €8 million over three years. Ultrasound, radar, LiDAR, and visible-light cameras are […] >>

Researchers from IRIG and Leti joined forces with a team from Switzerland* to obtain lasing at temperatures as low as 273 K (0° C) using a slightly deformed germanium/tin (GeSn) alloy resonator. Emission in the infrared spectrum is generated by optical pumping. This achievement marks a new advance toward germanium lasers integrated on silicon. The […] >>

IRIG’s pulse tube cryocoolers were developed in the early 2000s and transferred to Thales in 2005. But the tiny devices are still making news! The 30 sensors that make up the DESI* spectroscope, which will create a giant map of the sky, is cooled by the cryocoolers. Five years from now DESI will have produced […] >>
