Analysis of the linear kink effect in partially depleted SOI nMOSFET's
(2005-09-07) AGOPIAN, P. G.; MARTINO, J. A.; SIMOEN, E.; CLAEYS, C.
In this work, the occurrence of the linear kink effect (LKE) in PD SOI nMOSFETs is investigated experimentally and by two-dimensional simulations. The experimental dependence of the LKE on the drain voltage and the channel length is reported, showing a reduction of the second peak in the transconductance when the transistor channel length decrease. By two-dimensional numerical simulations, the impact of various parameters on this second peak has been studied, namely, the gate current level, the carrier lifetime, the increase of the body potential and the threshold voltage variation.
