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. The absence of the buried layer results in the reduced electrostatic coupling …
