Comparative Analysis of FD-DMDG SON MOSFET over FD DMDG SOI MOSFET
Abstract: AbstractIn the recent past, Silicon-on-Insulator (SOI) shows better device performance in comparison to bulk Silicon devices but it still suffers from different short channel effects (SCEs). Recently a structure, Silicon on Nothing (SON), has been suggested and investigated. It is structured to be capable of substantial reduction of SCEs and present better electrical characteristics in comparison to SOI.
