WebThe thickness of the fin (measured in the direction from source to drain) determines the effective channel length of the device. The wrap-around gate structure provides a better … WebAs the gate surrounds only three sides of the channel in finFETs, one side is left without gate control. When the gate length is reduced in finFETs, it creates short channel effects and more leakage currents through the ungated side of the device. However, in GAAFETs, all sides of the channel are enclosed by gate material.

Web2 days ago · There are a number of ways to mitigate the SCE, but they all have trade-offs. One way is to use a tri-gate (FinFET) structure. The FinFET structure helps to reduce the SCE by increasing the channel length of the transistor. Another way to mitigate the SCE is to use a high-k dielectric. WebThis difference with respect to the n- FinFET can be explained because the channel resistance is higher (lower mobility) and the series resistance is lower (see Figs. 4 and 5) for p-FinFET’s. Of course, as the channel length of the FinFETs de- creases, the series resistance value becomes relatively larger than the channel resistance ... fintree founder
