Resumo
In this work, the influence of the twin-gate structure on the gate-induced floating body effects in thin gate oxide partially depleted (PD) silicon-on-insulator (SOI) nMOSFETs is investigated through two-dimensional numerical simulations, which are validated by experimental results. The asymmetric behavior of the body potential with the interchange of the master and slave transistor of the twin-gate structure will be shown, as well as the relation between the total resistance and the effective mobility degradation factor. It will be demonstrated that a similar reduction of the linear kink effect is obtained in a twin-gate structure and in a conventional SOI transistor with an external resistance in series. © 2006 Elsevier Ltd.
