CEA-Leti Will Present Gains in Ultimate 3D, RF & Power, and Quantum & Neuromorphic Computing with Emerging Devices
CEA-Leti papers at IEDM 2023, Dec. 9-13, in San Francisco, will present results in multiple fields, including ultimate 3D advances in radio frequency, such as performance improvement at cryogenic temperature.
The institute will present nine papers during the conference this year. Two presentations will highlight a breakthrough in 3D sequential integration and results pushing GaN/Si HEMT closer to GaN/SiC performance at 28 GHz:
“3D Sequential Integration with Si CMOS Stacked on 28nm Industrial FDSOI with Cu-ULK iBEOL Featuring RO and HDR Pixel”, reports the world-first 3D sequential integration of CMOS over CMOS with advanced metal line levels, which brings 3DSI with intermediate BEOL closer to commercialization.
“6.6W/mm 200mm CMOS Compatible AlN/GaN/Si MIS-HEMT with In-Situ SiN Gate Dielectric and Low Temperature Ohmic Contacts” reports development of CMOS compatible 200mm SiN/AlN/GaN MIS-HEMT on silicon substrate that brings GaN/Si high electron mobility transistors (HEMT) closer to GaN/SiC performance at 28 GHz in power density. It also highlights that SiN/AlN/GaN on silicon metal-insulated semiconductor (MIS-HEMT) is a potential candidate for high power Ka-band power amplifiers.
