Characteristic Study of SOI eSiGe Techonology

This paper presents a detailed study of SOI source/drain embedded SiGe (eSiGe) technology with a focus on parasitic characteristics. It shows that eSiGe can appreciably suppress on-state floating body effect and improve device exterior resistance. Although eSiGe only physically addresses P-FET, junction capacitances of both P- and N-FETs can be impacted.
