Various methods out-of CFET was compared in terms of electrothermal attributes and you may parasitic capacitance. A comparison between various other PDN measures with a BTR shows brand new abilities advantage of CFET structures. Right here, the new dictate of various details on CFET are learnt.
The Id – Vg curves shown in Figure 2a, the gm – Vgs and gm / Id – Vgs curves for the NFET jovens CroГЎcia mulheres procurando homens 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 propose a great BTR technology that creates another reasonable-thermal-resistance street regarding drain side to the base, reducing the thermal opposition amongst the sink and the base. Running on the fresh BTR tech, the newest Roentgen t h of all actions is quite smaller and you may the brand new I o letter is increasedpared towards traditional-CFET, the new R t h of your own BTR-CFET are faster of the cuatro% to possess NFET and nine% getting PFET, and its particular We o letter was increased of the dos% to possess NFET and you may eight% getting PFET.
Shape 13a–d let you know the brand new R t h and you will ? Roentgen t h % for various opinions of W n s and you can L elizabeth x t between your BTR and you can BPR. This new increment from the W n s reduces the brand new Roentgen t h from the extension of the channel’s temperature dissipation area. The fresh new increment on L age x t strongly advances the Roentgen t h by variation on the spot, which escalates the temperature dissipation path from the highest thermal opposition channel, once the shown inside the Profile fourteen. In the event that W n s expands, this new ? Roentgen t h % grows from the big thermal conductivity urban area. If the L age x t expands, the brand new ? Roentgen t h % of the NFET decrease. The reason being the newest hot spot is actually after that away from the BTR.
