Abstract

This paper presents a 2-D analytical model of Dual-Material Double Gate Silicon-On-Nothing (DMDG SON) MOSFET. In order to obtain the surface potential variation of the device, 2-D Poisson’s equation with proper boundary conditions is solved. Electric field and threshold voltage are calculated for the device and the various short channel effects like DIBL, threshold voltage roll-off, hot carrier effect are examined. The close agreement between the calculated and simulated values obtained from a 2-D device simulator namely ATLAS validate the proposed model.
