Different methods regarding CFET is actually opposed with respect to electrothermal characteristics and you can parasitic capacitance. An assessment between some other PDN measures with an effective BTR shows the new show benefit of CFET tissues. Here, the brand new determine various variables towards the CFET are 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.

We recommend a BTR technical that induce various other lower-thermal-opposition road regarding the drain side towards the base, decreasing the thermal opposition between your sink and bottom. Powered by the new BTR tech, brand new Roentgen t h of all of the strategies is quite faster and you can the fresh I o letter try increasedpared into antique-CFET, the brand new R t h of BTR-CFET is smaller by cuatro% to own NFET and you can 9% to possess PFET, and its particular We o n are improved from the dos% to have NFET and you may eight% to own PFET.

Contour 13a–d show the brand new Roentgen t h and you will ? Roentgen t h % for different thinking regarding W n s and you can L e x t within BTR and you can BPR. The fresh increment in the W letter s lowers the R t h of the extension of your channel’s temperatures dissipation urban area. The fresh new increment regarding the L e x t highly increases the R t h by the variation regarding hot spot, hence increases the temperatures dissipation street from the higher thermal resistance route, once the found during the Profile fourteen. If W n s develops, new ? Roentgen t h % develops by large thermal conductivity urban area. If L age x t expands, the latest ? Roentgen t h % of the NFET minimizes. This is because the brand new hot-spot is actually next from the BTR.
