The feasibility of geometric magnetoresistance (MR) measurement from linear to saturation operation regime is demonstrated in ultrathin body and BOX fully depleted silicon-on-insulator devices from 14-nm technology node. Besides, we propose a new physical compact model for MOSFET drain current under high field transport, which reproduces experimental MR mobility from linear to saturation operation region and serves as the basis for a new extraction method of carrier saturation velocity. A benchmarking with state-of-the-art saturation velocity extraction methodologies is also conducted. Our saturation velocity results indicate that, for this technology, nonstationary transport prevails as manifested by an overshoot velocity behavior, still far from the ballistic limit.
