Various methods regarding CFET are opposed with regards to electrothermal characteristics and parasitic capacitance. A comparison between other PDN strategies with a BTR shows the newest efficiency benefit of CFET buildings. Right here, new influence various parameters toward CFET are well analyzed.
The Id – Vg curves shown in Figure 2a, the gm – Vgs and gm / Id – Vgs curves for the NFET and PFET shown in Figure 2b,c and the gm – Vgs and gm / Id – Vgs curves for the NFET and PFET with SHE shown in Figure 2d,e ensure the rationality of the device parameter settings of the CFET in a double-fin structure . Reference_N means the reference data of the NFET. TCAD_N means the TCAD simulation result of the NFET. SHE_N means the TCAD simulation result of the NFET with a self-heating effect, and the same applies for the PFET. The work functions of NFET and PFET were adjusted to match the off-current and the threshold voltage. By default, the velocity in the Drift-Diffusion (DD) simulation cannot exceed the saturation value, which is the reason for the underestimation of the drive current. the DD simulations can be adjusted to match the Monte Carlo (MC) simulation results by increasing the saturation velocity in the mobility model. Increasing the v s a t value of the NFET and the PFET to 3.21 ? 10 7 cm / s and 2.51 ? 10 7 cm / s , respectively, which are three times the original value, leads to a better fitting of the Id – Vg curves. The Id – Vg curves of double-fin-based CFET with SHE are also shown. When the V g s rises, the I d rises. The increment in the I d increases the temperature, which causes the degradation of the I d , causing the decrement of the g m . The SHE also degrades the device performance, which can be observed by the decrement of the g m / I d . The calibrated model based on the DD is a simplified scheme to avoid the computationally expensive SHE approach. Sheet-based CFET has been proven to have a better performance than fin-based CFET; the following research has been established on sheet-based CFET with similar parameters and models. BTR technology has the potential to improve the performance of the CFET. Figure 3 shows the process flow of sheet-based CFET with BTR.
I recommend good BTR technical that induce various other reasonable-thermal-opposition roadway in the sink top towards base, reducing the thermal opposition between the sink and base. Powered by the new BTR technology, the fresh R t h of all of the actions is quite reduced and you can the latest We o n is actually increasedpared on the old-fashioned-CFET, the latest Roentgen t h of your own BTR-CFET was faster because of the cuatro% to have NFET and nine% having PFET, and its particular I o letter was enhanced because of the dos% to possess NFET and you can seven% for PFET.
Contour 13a–d tell you the fresh new R t h and you may ? Roentgen t h % for several thinking of W n s and you will L elizabeth x t amongst the BTR and you can BPR. The fresh new increment regarding the W letter s reduces this new Roentgen t h from the expansion of the channel’s temperature dissipation city. Brand new increment in the L elizabeth x t firmly advances the Roentgen t h by the type in the hot-spot, and therefore boosts the temperatures dissipation street on large thermal opposition route, since found from inside the Contour fourteen. When the W letter s increases, this new ? Roentgen t h % develops by large thermal conductivity area. When the L e x t increases, the latest ? Roentgen t h % of NFET minimizes. It is because the fresh spot try next off the BTR.
It is familiar with render an estimated service of one’s supplier transportation, that explains the large differences demonstrated within the Contour 2d,e
