In depth characterization of hole transport in 14nm FD-SOI pMOS devices

In this paper, we studied hole transport in highly scaled (down to 14nm-node) FDSOI devices, from 77K to 300K in the coupling condition. We studied mobility enhancement by Ge% and back biasing. Then, mobility degradation in short channel devices was intensively analysed and additional scattering mechanisms were revealed in terms of their origin and location.
