We have been studying on subthreshold characteristics of SOI MOSFETs in terms of substratebias dependence, using a 1-D Poisson equation on an SOI multi-layer structure for estimatingstructural parameters of real devices[1]. Here, we consider quantum mechanicaleffects in the electron inversion layer of thin SOI MOSFETs, implementing a self-consistentsolver of Poisson and Schrödinger equations in a 1-D subthreshold simulator. From results ofsimulations, we have concluded that quantum mechanical effects need to be considered inanalizing thin SOI devices
