Abstract :
In this paper, we present a novel fin and recess channel MOSFET (FiReFET) which has low leakage current as well as excellent current drivability. In contrast to the bulk-FinFET, the FiReFET has trench gates which can lead to the reduction of the off-state leakage current without the punch-through stop implantation. Furthermore, it is possible to enhance the on-state current against the RCAT using the thin fin channel and the wide source/drain region.
