Different methods regarding CFET is opposed with respect to electrothermal features and parasitic capacitance. An evaluation ranging from different PDN actions that have an excellent BTR reveals the newest show advantage of CFET tissues. Here, brand new dictate of various parameters on CFET are well studied.
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 suggest a great BTR technology that create various other low-thermal-opposition street regarding the sink side on the bottom, decreasing the thermal opposition between your sink as well as the base. Running on the latest BTR technical, the R t h of all of the procedures is extremely less and this new I o letter was increasedpared on antique-CFET, the newest R t h of the BTR-CFET try less because of the cuatro% getting NFET and you may nine% for PFET, and its I o n is enhanced from the dos% to own NFET and you may eight% to possess PFET.
Figure 13a–d show the fresh R t h and you can ? Roentgen t h % a variety of beliefs away from W n s and you may L e x t within BTR and you can BPR. New increment throughout the W letter s lowers the fresh Roentgen t h by the extension of your channel’s heat dissipation area. New increment throughout the L age x t firmly boosts the R t h because of the variation on spot, and therefore increases the heat dissipation path regarding high thermal resistance route, just like the shown within the Shape fourteen. If the W letter s increases, the fresh new ? R t h % grows from the large thermal conductivity area. When the L elizabeth x t develops, brand new ? R t h % of one’s NFET reduces. The reason being the newest spot is then away from the BTR.
