Planar FDSOI technology for sub 22nm nodes

Recent device developments and achievements have shown that undoped channel planar Fully depleted SOI devices are becoming a serious alternative to Bulk technologies for 22nm node and below. This planar option seems to be even easier than non planar FinFET devices. This paper will report the main results obtained with this technology and will compare these results with the state of the art of Bulk and FinFET technologies: electrostatic performance, drivability, variability and scalability will be presented through silicon data and TCAD analysis. Challenges with respect to Multiple VT aspects and SRAM will also be reported.
