Thomas Ernst

Thomas Ernst is a Chief Scientist and VP Research at CEA LETI since 2018, leading long-term research strategy and partnerships in microelectronics. He co-led the French Electronics Program (2022–2027) and previously worked at CEA-Leti within the Crolles Alliance (2002–2007), developing advanced transistor technologies. His career began with a research contract at STMicroelectronics (1997–2000) during his PhD at CNRS, where he published groundbreaking work on ultra-thin SOI transistors.

• Key Contributions: Development of SiGe/Ge transistors, strained SOI technology, and the first functional multichannel GAA transistor (now industry-standard for 2–3nm CMOS).
• Research Focus: Microelectronics, nanoelectromechanical systems (NEMS), CMOS scaling, and device modeling.
• Awards: CEA Fellow (2022), IEEE Senior (2015), and multiple IEEE/ESSDERC Best Paper awards.
