چکیده

MOSFETs with gate length down to 17 nm are reported. To suppress the short channel effect, a novel self-aligned double-gate MOSFET, FinFET, is proposed. By using boron-doped Si0 4Ge0 6 as a gate material, the desired threshold voltage was achieved for the ultrathin body device. The quasiplanar nature of this new variant of the vertical double-gate MOSFETs can be fabricated relatively easily using the conventional planar MOSFET process technologies.

Sub - 50 nm P - Channel FinFET

High-performance PMOSFETs with sub-50–nm gate-length are reported. A self-aligned double-gate MOSFET structure (FinFET) is used to suppress the short-channel effects. This vertical double-gate SOI MOSFET features: 1) a transistor channel which is formed on the vertical surfaces of an ultrathin Si fin and controlled by gate electrodes formed on both sides of the fin; 2) two gates which are self-...

High performance PMOSFETs with a gate length as short as 18-nm are reported. A self-aligned double-gate MOSFET structure (FinFET) is used to suppress the short channel effect. The 45 nm gate-length PMOS FinFET has an Idsat of 410 PA/Pm (or 820 PA/Pm depending on the definition of the width of a double-gate device) at Vd = Vg = 1.2 V and Tox = 2.5 nm. The quasi-planar nature of this variant of t...

FinFET Architecture Analysis and Fabrication Mechanism

In view of difficulties of the planar MOSFET technology to get the acceptable gate control over the channel FinFET technology based on multiple gate devices is better technology option for further shrinking the size of the planar MOSFET [1]. For double gate SOIMOSFET the gates control the channel created between source and drain terminal effectively. So the several short channel effects like DI...
