Various methods off CFET are compared in terms of electrothermal properties and you will parasitic capacitance. An evaluation between other PDN strategies which have a great BTR reveals brand new overall performance advantage of CFET architecture. Here, the dictate of various details on the CFET are 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 good BTR technology that induce other lowest-thermal-resistance roadway in the drain side towards the bottom, reducing the thermal resistance between the drain in addition to bottom. Powered by this new BTR tech, the newest R t h of all measures may be very shorter and you will new We o letter is increasedpared into the traditional-CFET, brand new Roentgen t h of your own BTR-CFET is less from the 4% having NFET and you will nine% having PFET, as well as We o n try improved from the 2% to have NFET and seven% for PFET.
Figure 13a–d show the latest R t h and you may ? R t h % for various thinking of W letter s and you may L elizabeth x t amongst the BTR and you may BPR. The brand new increment on W n s lowers this new Roentgen t h of the expansion of channel’s temperatures dissipation area. The latest increment about L age x t strongly boosts the R t h by adaptation regarding hot spot, and therefore escalates the temperatures dissipation roadway regarding the higher thermal opposition channel, just like the found in the Figure fourteen. In the event that W letter s grows, the latest ? R t h % increases from the huge thermal conductivity city. If the L age x t grows, the fresh new ? Roentgen t h % of one’s NFET reduces. Simply because the new hot spot is then from the BTR.
