- Impact of series resistance on the drain current variability in inversion mode and junctionless nanowire transistors(2023-10-05) SILVA, L. M. B. DA; Marcelo Antonio Pavanello; CASSÉ, M.; BARRAUD, S.; VINET, M.; FAYNOT, O.; Michelly De Souza© 2023 Elsevier LtdThis work analyzes the influence of source-drain series resistance variability over the drain current in junctionless and inversion mode nanowire transistors. A comparison between drain current and Y-function variability is presented using experimental data of nanowires with different widths and channel lengths. The source-drain series resistance variability is also presented. The results indicates that source-drain series resistance influence is higher on drain current variability for junctionless than inversion mode nanowire transistors.
- Methodology to separate channel conductions of two level vertically stacked SOI nanowire MOSFETs(2018) Paz B.C.; Casse M.; Barraud S.; Reimbold G.; Vinet M.; Faynot O.; Pavanello M.A.© 2018 Elsevier LtdThis work proposes a new method for dissociating both channel conductions of two levels vertically stacked inversion mode nanowires (NWs) composed by a Gate-All-Around (GAA) level on top of an Ω-gate level. The proposed methodology is based on experimental measurements of the total drain current (IDS) varying the back gate bias (VB), aiming the extraction of carriers’ mobility of each level separately. The methodology consists of three main steps and accounts for VB influence on mobility. The behavior of non-stacked Ω-gate NWs are also discussed varying VB through experimental measurements and tridimensional numerical simulations in order to sustain proposed expressions of mobility dependence on VB for the bottom level of the stacked structure. Lower mobility was obtained for GAA in comparison to Ω-gate. The procedure was validated for a wide range of VB and up to 150 °C. Similar temperature dependence of mobility was observed for both Ω-gate and GAA levels.
