![]() Due to the improved channel dimensions and layout, leakage current is marginal and short-channel effects are inconsequential. GAAFET transistors provide greater administration of the gate and make the devices highly efficient. Furthermore, GAA technology has helped to reduce voltage scaling even further which was limited in FinFET due to design restrictions. If the producers want they can reduce the device size thereby reducing the drive current. This provides engineers better command over the device characteristics such that a wide sheet will drive more current but increase the overall size of the cost. The number and width of the nanosheets can be controlled. However, with the decreased size, the cost of production has not reduced remarkably. The control over leakage current has reduced and the short-channel effects are hampering the operating conditions of the transistor.Ĭurrent node processing technologies allow the fabrication of 3nm FinFETs. The fabrication technology is ever-evolving, and companies had no choice but to switch to FinFETs, but it seems that FinFETs have reached their size thresholds such that reducing the size is getting more difficult and performance improvement is not considerable. FinFETs were highly scalable due to the design parameters and reduced the leakage currents, and provided faster switching times. ![]() According to ×, (2) and a coefficient is assigned to each group where is the sizing factor of transistors. Then the channel width of transistors in group is considered to be equal to, where 1, 2,. FinFETs provided a way to better control the dynamics of the device by introducing a 3-D configuration rather than a planar device. At the beginning, all the transistors of a circuit are categorized on the basis of the rules of grouping transistors. But, the scaling of transistors brought about intensified short channel effects, leakage due to quantum tunneling, and mobility degradation. With the advent of newer manufacturing processes and the need for efficient devices, the device sizes have become smaller.
