Abstract :
We present measurements and parameter extraction performed on 28nm UTBB FDSOI MOSFETs with two different Back Plane configurations (p-type and n-type BP). The change in BP doping and work function affects directly the back-channel characteristics and indirectly, via interface coupling, the front-channel properties. We investigate the parameters relevant for the design of ESD protection devices: threshold voltage shift and electron mobility in long and short transistors.
