Gallium nitride (GaN) is fi nally giving silicon a run for its money for use in power transistors capable of switching hundreds of volts. What has changed? Until now, GaN fabrication processes were simply cost prohibitive. Researchers at Leti are on the verge of overcoming cost concerns with their recent 650 V “normally-on” transistor, fabricated […] >>

In R&D conducted under the EU ML2 (MultiLayer MicroLab) project, Leti recently transferred a process to Germany’s Fraunhofer Institute that functionalizes long spools (over 100 meters) of PMMA plastic sheets by grafting biological molecules onto the material. Oxygen plasma treatment is used to modify the plastic’s surface, and then contactless printing is used to graft […] >>

Since this summer, Leti has been in charge of Inspire, an industrial evaluation program for nanoimprint lithography. The program’s launch was attended by over ten manufacturers, including Toshiba, Arkema, and STMicroelectronics. In addition, Austria’s EVG, who already hosts demo campaigns, plans to provide the program with one of its most recent nanoimprint machines by the […] >>

This summer, researchers at Leti fabricated the world’s first M&NEMS micro-accelerometers on 300 mm wafers, sending three crucial messages to the academic and industrial research and development communities. First, the research proved that MEMS, or microelectromechanical systems, can be fabricated on 300 mm wafers, the largest format used in microelectronics. This advance will give MEMS […] >>

Grenoble-based startup Arnano, which has traditionally addressed the B2B market, raised more than €45,000 for its Fahrenheit2451 project from 329 donors in 22 countries on Kickstarter, putting its name on the map in consumer markets. A 2009 spinoff of Leti, Arnano manufactures and engraves sapphire memory capable of withstanding all sorts of abuse, including temperatures […] >>
