Packan et al., IEDM 2009 XTEM images with the same scale fabricated top-gated carbon nanotube field-effect transistors with a gate length of 5 nm. In the current mirrors, a higher transistor gate length is beneficial, for a better matching of the mirror’s currents. When normalized to the actual fin perimeter, N-FinFET and P-FinFET have 1200 and 915 ¿A/¿m drive current respectively at 100 nA/¿m leakage under 1V. A 3D Tri-Gate transistor looks a lot like the planar transistor but with one fundamental change. All the devices described in this work has a gate length L g of 10 μm, a gate-drain distance L gd of 5 μm, a gate-source distance L gs of 5 μm. Novel 10-nm Gate Length MoS 2 Transistor Fabricated on Si Fin Substrate Abstract: To allow the use of molybdenum disulfide (MoS 2 ) in mainstream Si CMOS manufacturing processes for improved future scaling, a novel MoS 2 transistor with a 10-nm physical gate length created using a p-type doped Si fin as the back-gate electrode is presented. When the industry talks about 0.18u and 0.13u processes, they're talking about the gate length (channel length) of a typical MOS transistor. For many generations, the switching speed – and hence the performance of the transistor – could be increased by shrinking the gate length (L) and by applying stress to improve the channel mobility. Thin graphene contacts helped maintain electrostatic control. Instead of having a planar inversion layer (where electrical current actually flows), Intel's 3D Tri-Gate transistor creates a three-sided silicon fin that the gate wraps around, creating an inversion layer with a much larger surface area. The energy band diagram of an ideal p-type substrate MOS capacitor at zero bias is shown in Figure 3.2.In an ideal MOS capacitor, the metal work function, ϕ m, is equal to the semiconductor work function, ϕ s.Therefore, when the Fermi level of the semiconductor, E FS, is aligned with the Fermi level of the gate, E Fm, there is no band bending in any region of the MOS capacitor.
1 Structure and performance of 10-nm CNT CMOS FETs. One option for extending the performance of complementary metal-oxide semiconductor (CMOS) devices based on silicon technology is to use semiconducting carbon nanotubes as the gates.

The smaller your transistors, the more you can fit on a chip, and the faster and more efficient your processor can be.
To reach the >3GHz goal, circuit simulations show that 60nm gate length and 1.5nm gate-oxide thickness are required for the 130nm technology node. We present a high-performance and low-power FinFET module at 25 nm gate length. (B) Transfer characteristics (drain current I ds versus gate voltage V gs) of typical CMOS FETs fabricated on a s-SWCNT with a diameter of 1.3 nm at a drain bias V ds = ±0.4 V. Enlarge. We present a high-performance and low-power FinFET module at 25 nm gate length. We demonstrated a 1-nanometer-gate transistor, showing that with the choice of proper materials, there is a lot more room to shrink our electronics.” The key was to use carbon nanotubes and molybdenum disulfide (MoS 2), an engine lubricant commonly sold in auto parts shops. – Transistor performance has been boosted by other means. Figure 7 is the gate C-V characteristics measured from a multiple-fin device with large gate area (10x10µm2). (A) TEM images showing the cross sections of a p-type FET, n-type FET, and gate stack; gate length 10 nm, channel length 20 nm. The 60nm transistor requires a significant acceleration of the transistor feature size relative to the technology and light source. transistor channel length and gate -oxide thickness (Figure 2). However, there are 3 ways to measure gate length: 1) from the photo mask, 2) actual length between source and drain edges, and 3) the effective gate length which takes into account encroachment and LDD features underneath the gate.
