Advanced MOSFETs exploit the carrier confinement to suppress the short-channel effect, which is realized by reducing the bulk layer thickness. The ongoing developments of the multi-gate MOSFET as well as the fully-depleted SOI-MOSFET with ultra thin silicon layer are proved to be applicable beyond the 50nm technology node. However, these advanced devices suffer from the floating-body effect caused by an unfixed body node, which plays an important role for the device performances. Here we present a modeling approach, based on a consistent potential description, how to simplify the problem of solving the Poisson equation with the floating-body node. The solution to the charge storage within the substrate is also discussed.
