As the industry moved to advanced technology nodes (≀ 22 nm), FinFETs became the standard device used in digital and analog IC design due to their superior electrostatic control, low leakage, and scalability.

Detailed Explanation

The text explains that with advancements in technology, particularly when moving to nodes that are 22 nanometers or smaller, FinFETs (Fin Field Effect Transistors) have become the go-to choice for creating integrated circuits. This is because FinFETs offer better control over electrical signals, reduce leakage currents (unwanted flow of electricity), and are more scalable for future technology demands.

Examples & Analogies

Think of FinFETs like switching from traditional incandescent light bulbs to energy-efficient LED bulbs. Just as LEDs are better at converting electricity into light while wasting less energy, FinFETs are more efficient in handling electrical signals and reducing power loss in circuits.
